0ed3ef52af the MinPad argument to PadToColumn only really makes sense to be 1, 
just remove the argument and replace it with 1.

4d57894a63 Take the fast path for any named value and any GlobalValue, which doesn't 
need TypePrinting despite being a subclass of Constant. This fixes
compile-time problems especially visible on 403.gcc when -asm-verbose is
enabled.

d559e66749 Fix a 4x slowdown in llc -asm-verbose caused by the use of 
WriteAsOperand in more places.

Now that more things are using WriteAsOperand, its behavior of
constructing a TypePrinting object and populating it with strings for all
the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

ea15a77701 Change the indentation for LLVM Assembly files from 1 tab to 2 spaces. 
This is vaguely consistent with LLVM's own source code, but more
importantly it lets more lines stay within 80 columns.

llvm-svn: 78879
 2009-08-13 01:41:52 +00:00

9c9c3f30bd Now that numbered types have their number printed, it's no longer 
interesting to print the number in a comment. Numbered instructions
don't need their number in a comment either.

Also, tidy up newline printing.

4ee8471442 Extend the AsmWriter to print unnamed numbered types as "%0 = type ..." 
and unnamed numbered global variables as "@0 = global ...". Extend the
AsmParser to recognize these forms.

llvm-svn: 78859
 2009-08-12 23:32:33 +00:00
Dan Gohman
9b4700f3ce Make AsmWriter more careful with formatted_raw_ostream so that 
it doesn't leave the underlying stream in unbuffered mode when
the stream was originally buffered.

Also, change WriteAsOperand back to plain raw_ostream. This
lets it work for either formatted_raw_ostream or plain
raw_ostream, so that it doesn't have to force a buffer flush
on a plain raw_ostream.

9f80d2be6b Make LLVM Assembly dramatically easier to read by aligning the comments, 
using formatted_raw_ostream's PadToColumn.

Before:

bb1:            ; preds = %bb
  %2 = sext i32 %i.01 to i64            ; <i64> [#uses=1]
  %3 = getelementptr double* %p, i64 %2         ; <double*> [#uses=1]
  %4 = load double* %3, align 8         ; <double> [#uses=1]
  %5 = fmul double %4, 1.100000e+00             ; <double> [#uses=1]
  %6 = sext i32 %i.01 to i64            ; <i64> [#uses=1]
  %7 = getelementptr double* %p, i64 %6         ; <double*> [#uses=1]

After:

bb1:                                        ; preds = %bb
  %2 = sext i32 %i.01 to i64                ; <i64> [#uses=1]
  %3 = getelementptr double* %p, i64 %2     ; <double*> [#uses=1]
  %4 = load double* %3, align 8             ; <double> [#uses=1]
  %5 = fmul double %4, 1.100000e+00         ; <double> [#uses=1]
  %6 = sext i32 %i.01 to i64                ; <i64> [#uses=1]
  %7 = getelementptr double* %p, i64 %6     ; <double*> [#uses=1]

Several tests required whitespace adjustments.

Getelementptrs that are defined to wrap are virtually useless to

all intermediate addresses are within bounds. I'm going to take
a different approach.

6ec578688d Reapply my previous asmprinter changes now with more testing and two 
additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

b0e0d16efb Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr" 
to symbols instead of doing it with "printSuffixedName".  This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.

This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.

Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

2a6bb9bc51 Change the internal interface to makeNameProper to take a bool that 
indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.

6460e403a7 rename Memo/Count to AnonGlobalIDs/NextAnonGlobalID to be more 
descriptive.  Thange them to keep track of the ID of a global that is
assigned, not the first mangled name returned for it.  Without doing this,
we are required to always use the same suffix for a global that gets 
mangled.  This means that we can mangle the same global once with $stub
and another time with $non_lazy_ptr or whatever.
