Rafael Espindola 8a3a7923eb Define generic 1, 2 and 4 byte pc relative relocations. They are common 
and at least the 4 byte one will be needed to implement the .cfi_* directives.

 2010-11-28 06:51:19 +00:00
Bob Wilson 04b2c94205 Another minor refactoring for VLD1DUP instructions. 
The op11_8 field is the same for all of them so put it in the instruction
classes instead of specifying it separately for each instruction.

llvm-svn: 120234
 2010-11-28 06:51:15 +00:00

llvm-svn: 120203
 2010-11-27 08:22:29 +00:00
Owen Anderson 8ba5f39f70 Second attempt at fixing the performance regressions introduced 
by my recent GVN improvement.  Looking through a single layer of
PHI nodes when attempting to sink GEPs, we need to iteratively
look through arbitrary PHI nests.

llvm-svn: 120202
 2010-11-27 08:15:55 +00:00
Daniel Dunbar 65dc891942 raw_ostream::write_escaped: Add a UseHexEscapes argument.

llvm-svn: 120198
 2010-11-27 07:19:41 +00:00

 2010-11-27 07:12:02 +00:00

 2010-11-27 06:35:16 +00:00
Bob Wilson 3a63f9d852 Fix incorrect scheduling itineraries for NEON vld1/vst1 instructions. 
I added these instructions recently but I have no idea where these "1"
values in the NextCycles field came from.  As far as I can tell now,
these instruction stages are clearly intended to overlap.

llvm-svn: 120193
 2010-11-27 06:35:09 +00:00
Daniel Dunbar 1df8d83a55 MC/Mach-O: Start stubbing out a Mach-O object file wrapper. 
llvm-svn: 120190
 2010-11-27 05:38:50 +00:00
Daniel Dunbar 4b128a5d4f Reduce nesting. 
llvm-svn: 120189
 2010-11-27 05:18:48 +00:00
Daniel Dunbar eab6e401fe MC/Mach-O: Migrate more constants into MachOFormat.h. 
llvm-svn: 120188
 2010-11-27 04:59:14 +00:00
Daniel Dunbar a5f50c16f7 MC/Mach-O: Switch to using MachOFormat.h. 
- I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

llvm-svn: 120187
 2010-11-27 04:38:36 +00:00
Daniel Dunbar 2263ca4834 MC/Mach-O: Introduce Object/MachOFormat for describing purely platform / machine 
independent information on the Mach object format, and move some stuff from
MachObjectWriter.cpp there.

llvm-svn: 120186
 2010-11-27 04:19:38 +00:00
Rafael Espindola bf4a4e4ad9 Remove the unused TheTarget member. 
llvm-svn: 120168
 2010-11-26 04:24:21 +00:00
Michael J. Spencer f13f442b1a Fix Whitespace. 
llvm-svn: 120166
 2010-11-26 04:16:08 +00:00
Jakob Stoklund Olesen a12095d26d Move tree navigation to a new Path class that doesn't have to be a template. 
The path also holds a reference to the root node, and that allows important
iterator accessors like start() and stop() to have no conditional code. (When
the compiler is clever enough to remove it.)

llvm-svn: 120165
 2010-11-26 01:39:40 +00:00
Rafael Espindola 7c2acd022e Use multiple 0x66 prefixes so that all nops up to 15 bytes are a single instruction. 
llvm-svn: 120147
 2010-11-25 17:14:16 +00:00
Benjamin Kramer aef5bd049f Namespacify. 
llvm-svn: 120146
 2010-11-25 16:42:51 +00:00
Rafael Espindola f8e127eaf6 Factor some code to parseSectionFlags and fix the default type of a section. 
llvm-svn: 120145
 2010-11-25 15:32:56 +00:00
Nick Lewycky b8de00ee07 Treat a call of function pointer like a load of the pointer when considering 
whether the pointer can be replaced with the global variable it is a copy of.
Fixes PR8680.

llvm-svn: 120126
 2010-11-24 22:04:20 +00:00
Rafael Espindola 9f75d5df0b Behave a bit more like gnu as and use the symbol (instead of the section) 
for any relocation to a symbol defined in a tls section.

llvm-svn: 120121
 2010-11-24 21:57:39 +00:00
Rafael Espindola 708ac4d6ad Relocate with the symbol if the relocation is of kind NTPOFF. 
Patch by David Meyer, I added the test.

llvm-svn: 120104
 2010-11-24 19:23:50 +00:00
Rafael Espindola e98d483b71 Fix and add tests for all cases in x86 and x86_64 where gnu as implicitly 
sets the type of a symbol to STT_TLS.

Wesley Peck 8ad3b25633 Updating MBlaze .mask and .frame directives to match GCC's output and fixing regression introduced in 120095 by checking MCStreamer::hasRawTextSupport. 
llvm-svn: 120097
 2010-11-24 16:32:35 +00:00
Wesley Peck 51917b868d 1. Fixing error where basic block labels were not being printed out when they need to be for the MBlaze backend because AsmPrinter::isBlockOnlyReachableByFallthrough does not take into account delay slots. 
2. Re-adding .mask and .frame directives in printed assembly.
3. Adding .ent and .end directives in printed assembly.
4. Minor cleanups to MBlaze backend.
