Brings the 'rebase' branch (52fc98dde, 163 commits, 11 authors) onto
current master (08ec54708) as a single squashed change. Authorship of
the underlying commits — predominantly Matt Pharoah (105), aglab2 (44),
plus smaller contributions from Denis Kopyrin, mudlord, devwizard,
Mr-Wiseguy, zoltanvb, twinaphex, libretroadmin, LibretroAdmin, and
Eric Warmenhoven — is recorded in the upstream 'rebase' branch
(libretro/parallel-n64).

Resolves conflicts in 6 files:

 .gitlab-ci.yml
   Kept linux-aarch64 + webOS jobs from master alongside osx-arm64,
   macOS HAVE_THR_AL, and iOS-disabled stanza from rebase HEAD.

 libretro/libretro.c
   Kept rebase's retro_core_options_v2 setup_variables; forward-ported
   astick_snap_active / astick_snap_max_angle /
   astick_snap_min_displacement_percent globals and their
   update_variables reads from PR #794, aligned to the registration key
   parallel-n64-astick-snap-max-angle (fixes the latent typo in #794
   where the read key omitted '-max-' and the option had no effect).

 libretro/libretro_core_options.h
   Added entries for astick-snap-angle-active, astick-snap-max-angle,
   and astick-snap-min-displacement-percent so the snap options surface
   under the v2 options system.

 mupen64plus-core/src/pi/pi_controller.c
   Kept both extern blocks: g_rom_size (master, security fix) and
   AllowUnalignedDMA / AllowLargeRoms / SdCardEmulationEnabled (rebase).

 mupen64plus-core/src/plugin/emulate_game_controller_via_libretro.c
   Added M_PI guard, snap externs, and the snap-angle math from PR #794
   into scale_joystick (refactored helper on rebase) rather than
   inputGetKeys_reuse.

 mupen64plus-core/src/rsp/rsp_core.c
   In read_rsp_regs2/write_rsp_regs2, combined SP_REGS2_COUNT bounds
   check (master) with SP_PC_REG masking (rebase).

 mupen64plus-rsp-paraLLEl/rsp_disasm.hpp
   Kept <stdint.h> rather than <cstdint> for consistency with the other
   headers in the paraLLEl-RSP module.

Also fixes a pre-existing inconsistency in the rebase branch that
strict GCC rejects under -Wincompatible-pointer-types:

 mupen64plus-core/src/si/game_controller.h
   Changed the get_gcn_input struct field's analogMode parameter from
   uint8_t to int, matching init_game_controller's parameter type,
   game_controller_gcn_get_input's signature, and the egcvip_get_gcn_input
   implementation (all three already used int).

[![Build Status](https://travis-ci.org/libretro/parallel-n64.svg?branch=master)](https://travis-ci.org/libretro/parallel-n64)
[![Build status](https://ci.appveyor.com/api/projects/status/iqe836smfugoy8ey/branch/master?svg=true)](https://ci.appveyor.com/project/bparker06/parallel-n64/branch/master)
# ParallelN64 (Parallel Launcher Edition)
# mupen64plus-libretro
A fork of [ParallelN64](https://git.libretro.com/libretro/parallel-n64) that adds the GLideN64 graphics plugin and some additional settings and features. Designed to be used with Parallel Launcher.
To enable a dynarec CPU core you must pass the WITH_DYNAREC value to make:
* make WITH_DYNAREC=x86
* make WITH_DYNAREC=x86_64
* make WITH_DYNAREC=arm
* make WITH_DYNAREC=aarch64
# Credits
New make options:
* USE_CXD4_NEW - use the most recent version of CXD4 that was verified on Android
* USE_SSE2NEON - enable SSE2 vectorized routines on ARMv7+ via hacked SSE2NEON library
The original ParallelN64 can be found here: https://git.libretro.com/libretro/parallel-n64
To build Android hardfp library with the new CXD4 RSP + NEON + Parallel RDP do:
* ndk-build -j8 USE_SSE2NEON=1 APP_ABI=armeabi-v7a-hard
Contributors for the modifications specific to this fork:
* [Matt Pharoah](https://gitlab.com/mpharoah)
* Black border fix for ParaLLEl
* Config to enable/disable unaligned DMA support
* 16:10 (SteamDeck) widescreen support for GLideN64
* Support for IS Viewer logging
* Support for changing the time on the RTC
* Support for storing the RTC state in savestates
* [Wiseguy](https://gitlab.com/Mr-Wiseguy)
* Raw gamecube controller support
* [Aglab2](https://gitlab.com/aglab2)
* MoltenVK (MacOS) support for ParaLLEl
* Black border fix for NTSC roms in GLideN64
* GLideN64 modifications for supporting old SM64 romhacks
* Support for detecting save types based on EverDrive headers
* Support for ROMs larger than 64 MiB
* Native ARM support for MacOS
* [devwizard](https://gitlab.com/devwizard64)
* Added support for SummerCart64 SD card emulation
To build Android arm64 library with the new CXD4 RSP + Parallel RDP + dynarec do:
* ndk-build APP_ABI=arm64-v8a

/* Function calling conventions.
* =============================
* Normally it is not necessary to specify to the compiler how to call
* a function - it just does it - however on x86 systems derived from
* Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
* and some others) there are multiple ways to call a function and the
* default can be changed on the compiler command line. For this reason
* libpng specifies the calling convention of every exported function and
* every function called via a user supplied function pointer. This is
* done in this file by defining the following macros:
*
* PNGAPI Calling convention for exported functions.
* PNGCBAPI Calling convention for user provided (callback) functions.
* PNGCAPI Calling convention used by the ANSI-C library (required
* for longjmp callbacks and sometimes used internally to
* specify the calling convention for zlib).
*
* These macros should never be overridden. If it is necessary to
* change calling convention in a private build this can be done
* by setting PNG_API_RULE (which defaults to 0) to one of the values
* below to select the correct 'API' variants.
*
* PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
* This is correct in every known environment.
* PNG_API_RULE=1 Use the operating system convention for PNGAPI and
* the 'C' calling convention (from PNGCAPI) for
* callbacks (PNGCBAPI). This is no longer required
* in any known environment - if it has to be used
* please post an explanation of the problem to the
* libpng mailing list.
*
* These cases only differ if the operating system does not use the C
* calling convention, at present this just means the above cases
* (x86 DOS/Windows sytems) and, even then, this does not apply to
* Cygwin running on those systems.
*
* Note that the value must be defined in pnglibconf.h so that what
* the application uses to call the library matches the conventions
* set when building the library.
*/
/* Symbol export
* =============
* When building a shared library it is almost always necessary to tell
* the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
* is used to mark the symbols. On some systems these symbols can be
* extracted at link time and need no special processing by the compiler,
* on other systems the symbols are flagged by the compiler and just
* the declaration requires a special tag applied (unfortunately) in a
* compiler dependent way. Some systems can do either.
*
* A small number of older systems also require a symbol from a DLL to
* be flagged to the program that calls it. This is a problem because
* we do not know in the header file included by application code that
* the symbol will come from a shared library, as opposed to a statically
* linked one. For this reason the application must tell us by setting
* the magic flag PNG_USE_DLL to turn on the special processing before
* it includes png.h.
*
* Four additional macros are used to make this happen:
*
* PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
* the build or imported if PNG_USE_DLL is set - compiler
* and system specific.
*
* PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
* 'type', compiler specific.
*
* PNG_DLL_EXPORT Set to the magic to use during a libpng build to
* make a symbol exported from the DLL. Not used in the
* public header files; see pngpriv.h for how it is used
* in the libpng build.
*
* PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
* from a DLL - used to define PNG_IMPEXP when
* PNG_USE_DLL is set.
*/
/* System specific discovery.
* ==========================
* This code is used at build time to find PNG_IMPEXP, the API settings
* and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
* import processing is possible. On Windows systems it also sets
* compiler-specific macros to the values required to change the calling
* conventions of the various functions.

/* png_info is a structure that holds the information in a PNG file so
* that the application can find out the characteristics of the image.
* If you are reading the file, this structure will tell you what is
* in the PNG file. If you are writing the file, fill in the information
* you want to put into the PNG file, using png_set_*() functions, then
* call png_write_info().
*
* The names chosen should be very close to the PNG specification, so
* consult that document for information about the meaning of each field.
*
* With libpng < 0.95, it was only possible to directly set and read the
* the values in the png_info_struct, which meant that the contents and
* order of the values had to remain fixed. With libpng 0.95 and later,
* however, there are now functions that abstract the contents of
* png_info_struct from the application, so this makes it easier to use
* libpng with dynamic libraries, and even makes it possible to use
* libraries that don't have all of the libpng ancillary chunk-handing
* functionality. In libpng-1.5.0 this was moved into a separate private
* file that is not visible to applications.
*
* The following members may have allocated storage attached that should be
* cleaned up before the structure is discarded: palette, trans, text,
* pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
* splt_palettes, scal_unit, row_pointers, and unknowns. By default, these
* are automatically freed when the info structure is deallocated, if they were
* allocated internally by libpng. This behavior can be changed by means
* of the png_data_freer() function.
*
* More allocation details: all the chunk-reading functions that
* change these members go through the corresponding png_set_*
* functions. A function to clear these members is available: see
* png_free_data(). The png_set_* functions do not depend on being
* able to point info structure members to any of the storage they are
* passed (they make their own copies), EXCEPT that the png_set_text
* functions use the same storage passed to them in the text_ptr or
* itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
* functions do not make their own copies.

Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
Polynomials over GF(2) are represented in binary, one bit per coefficient,
with the lowest powers in the most significant bit. Then adding polynomials
is just exclusive-or, and multiplying a polynomial by x is a right shift by
one. If we call the above polynomial p, and represent a byte as the
polynomial q, also with the lowest power in the most significant bit (so the
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
where a mod b means the remainder after dividing a by b.
This calculation is done using the shift-register method of multiplying and
taking the remainder. The register is initialized to zero, and for each
incoming bit, x^32 is added mod p to the register if the bit is a one (where
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
x (which is shifting right by one and adding x^32 mod p if the bit shifted
out is a one). We start with the highest power (least significant bit) of
q and repeat for all eight bits of q.
The first table is simply the CRC of all possible eight bit values. This is
all the information needed to generate CRCs on data a byte at a time for all
combinations of CRC register values and incoming bytes. The remaining tables
allow for word-at-a-time CRC calculation for both big-endian and little-
endian machines, where a word is four bytes.

/*
strm provides the memory allocation functions and window buffer on input,
and provides information on the unused input on return. For Z_DATA_ERROR
returns, strm will also provide an error message.
in() and out() are the call-back input and output functions. When
inflateBack() needs more input, it calls in(). When inflateBack() has
filled the window with output, or when it completes with data in the
window, it calls out() to write out the data. The application must not
change the provided input until in() is called again or inflateBack()
returns. The application must not change the window/output buffer until
inflateBack() returns.
in() and out() are called with a descriptor parameter provided in the
inflateBack() call. This parameter can be a structure that provides the
information required to do the read or write, as well as accumulated
information on the input and output such as totals and check values.
in() should return zero on failure. out() should return non-zero on
failure. If either in() or out() fails, than inflateBack() returns a
Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
was in() or out() that caused in the error. Otherwise, inflateBack()
returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
error, or Z_MEM_ERROR if it could not allocate memory for the state.
inflateBack() can also return Z_STREAM_ERROR if the input parameters
are not correct, i.e. strm is Z_NULL or the state was not initialized.

/*
Decode literal, length, and distance codes and write out the resulting
literal and match bytes until either not enough input or output is
available, an end-of-block is encountered, or a data error is encountered.
When large enough input and output buffers are supplied to inflate(), for
example, a 16K input buffer and a 64K output buffer, more than 95% of the
inflate execution time is spent in this routine.
Entry assumptions:
state->mode == LEN
strm->avail_in >= 6
strm->avail_out >= 258
start >= strm->avail_out
state->bits < 8
On return, state->mode is one of:
LEN -- ran out of enough output space or enough available input
TYPE -- reached end of block code, inflate() to interpret next block
BAD -- error in block data
Notes:
- The maximum input bits used by a length/distance pair is 15 bits for the
length code, 5 bits for the length extra, 15 bits for the distance code,
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
Therefore if strm->avail_in >= 6, then there is enough input to avoid
checking for available input while decoding.
- The maximum bytes that a single length/distance pair can output is 258
bytes, which is the maximum length that can be coded. inflate_fast()
requires strm->avail_out >= 258 for each loop to avoid checking for
output space.

inflate_fast() speedups that turned out slower (on a PowerPC G3 750CXe):

- Three separate decoding do-loops for direct, window, and wnext == 0
- Special case for distance > 1 copies to do overlapped load and store copy
- Explicit branch predictions (based on measured branch probabilities)
- Deferring match copy and interspersed it with decoding subsequent codes
- Swapping literal/length else
- Swapping window/direct else
- Larger unrolled copy loops (three is about right)
- Moving len -= 3 statement into middle of loop

Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by
the caller.
The length counts are used for other purposes as well, i.e. finding
the minimum and maximum length codes, determining if there are any
codes at all, checking for a valid set of lengths, and looking ahead
at length counts to determine sub-table sizes when building the
decoding tables.

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftrees.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

/* ARGB8888 scaler is split in two:
*
* First, horizontal scaler is applied.
* Here, all 8-bit channels are expanded to 16-bit. Values are then shifted 7
* to left to occupy 15 bits.
*
* The sign bit is kept empty as we have to do signed multiplication for the
* filter.
*
* A mulhi [(a * b) >> 16] is applied which loses some precision, but is
* very efficient for SIMD.
* It is accurate enough for 8-bit purposes.
*
* The fixed point 1.0 for filter is (1 << 14). After horizontal scale,
* the output is kept with 16-bit channels, and will now have 13 bits
* of precision as [(a * (1 << 14)) >> 16] is effectively a right shift by 2.
*
* Vertical scaler takes the 13 bit channels, and performs the
* same mulhi steps.
* Another 2 bits of precision is lost, which ends up as 11 bits.
* Scaling is now complete. Channels are shifted right by 3, and saturated
* into 8-bit values.
*
* The C version of scalers perform the exact same operations as the
* SIMD code for testing purposes.
