MSVC8 gives various compile error relating to templates that were changed
back in 2008, leading me to belive that no one is using it, and that there
is not point adding work arounds for a 9 year old compiler no one uses.
Makes the DCT code use constants of type float in expressions which only use
type float values otherwise. This silences some floating point conversion
warnings in the DCT code.
Since we take a float parameter and return a float value we will also just
work on float values all the way. This silences some float conversion
warnings.
This removes the need for a hardware keyboard to trigger the use
of the virtual keyboard via F7 if using the default event mapper.
As middle button is rarely used by games, this should not cause any
conflicts. Though to avoid this possibility, the event is passed to
the engine.
These issues were identified by the STACK tool.
By default, the C++ new operator will throw an exception on allocation
failure, rather than returning a null pointer.
The result is that testing the returned pointer for null is redundant
and _may_ be removed by the compiler. This is thus optimization
unstable and may result in incorrect behaviour at runtime.
However, we do not use exceptions as they are not supported by all
compilers and may be disabled.
To make this stable without removing the null check, you could qualify
the new operator call with std::nothrow to indicate that this should
return a null, rather than throwing an exception.
However, using (std::nothrow) was not desirable due to the Symbian
toolchain lacking a <new> header.
A global solution to this was also not easy by redefining "new" as "new
(std::nothrow)" due to custom constructors in NDS toolchain and various
common classes.
Also, this would then need explicit checks for OOM adding to all new
usages as per C malloc which is untidy.
For now to remove this optimisation unstable code is best as it is
likely to not be present anyway, and OOM will cause a system library
exception instead, even without exceptions enabled in the application
code.
This reverts commit b585addc23.
The allocation of MemoryPool's page memory is doing in MemoryPool::allocPage,
which uses ::malloc, thus we need to use ::free to free the page memory in
MemoryPool::freeUnusedPages.
Memory is allocated with new in Hashmap::allocNode() and incorrectly
freed with free() in ~MemoryPool() and freeUnusedPages().
Issue reported by Dr. Memory
The value_type is analogous to std::basic_string::value_type.
The unsigned_type on the other hand is an unsigned type of the value_type which
allows to obtain an character without nasty sign extension.
This fixes compilation of sword25's pluto with Visual Studio. The issue
has been revealed with commit 34169a81. The other data types are
defined in scummsys.h, thus only the missing int64 and uint64 defines
are set.
This is needed by the "Mirage" Wintermute game.
Vorbis can do backward seeking, thus we need to enable this for ZIP
streams. Since this can be a potentially slow operation, we throw a
warning (once per stream) when it occurs. Originally, SEEK_END seeks
in GZipReadStream were disabled by commit 9138128f. Refer to patch
#2050337 for more information.
Apparently their tools do not include __has_feature clang extension.
I've submitted the bugreport to them but in the meantime let's have this
define in the system.
The Russian translated versions of Neverhood have invalid unpacked
sizes for some compressed resources. This helps in identifying their
resource parameters more easily
