Chris Lattner 41e275dc8e simplify EmitFrameMoves to take BaseLabel in as a symbol

location" check to use symbol comparison.

Daniel Dunbar 34b8e553ea MC/Mach-O: PCrel relocations weren't using the right base address, they are 
relative to the fragment address, not its offset. This was masked by the text
section normally being at address 0.

 2010-03-13 02:38:00 +00:00
Daniel Dunbar 322fec671b llvm-mc: Support -n, useful for comparing -integrated-as output since the 
compiler may not lead with the text section.

llvm-svn: 98418

Daniel Dunbar 4689211583 llvm-mc: Support -arch as a simplified form of -triple.

Chris Lattner 81fe45d911 switch to the text section at the start of the .s file for darwin/x86 
targets.  This is a temporary hack for the .o file writer that Daniel
wants :)

Jeffrey Yasskin 2cc2476198 Delete MDNodes when LLVMContext is destroyed. Previous attempts: r97918, r97788. 
Tested: clang debug bootstrap, llvm-gcc bootstrap, `make check-lit`
after configuring with --with-llvmgccdir (and this did run the
FrontendC* tests this time)

Bob Wilson 947f04bad0 Change ARM ld/st multiple instructions to have variant instructions for 
writebacks to the address register.  This gets rid of the hack that the
first register on the list was the magic writeback register operand.  There
was an implicit constraint that if that operand was not reg0 it had to match
the base register operand.  The post-RA scheduler's antidependency breaker
did not understand that constraint and sometimes changed one without the
other.  This also fixes Radar 7495976 and should help the verifier work
better for ARM code.

There are now new ld/st instructions explicit writeback operands and explicit
constraints that tie those registers together.

other functionality on 403.gcc compiled at -O0.

Daniel Dunbar b86672059e MC/X86: Add an XFAIL test where we aren't matching the correct instruction 
because we don't understand how the specific instruction is doing sign
extension.

Bob Wilson 53149401ee Combine the code to build VLDM and VSTM instructions, since they are 
mostly the same.

Devang Patel ad591dc6af Do not overestimate code size reduction in presense of debug info.

John McCall 44c064be73 Check compatibility of vector types using their canonicalizations. 
Fixes an assertion arising C overload analysis, but really I can't imagine
that this wouldn't cause a thousand other uncaught failures.

Fixes PR6600.

Daniel Dunbar 12f1e32d59 MC/Mach-O: Implement initial support for relaxation. 
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)

Fariborz Jahanian c6140734c5 Fix a rare corner case bug which exposed a serious block API generation 
when initialized variable is a byref block variable and is referenced recursively
in the initializer (you guessed it, it is block implementation of
fibonacci number). Fix, on the other hand is trvial, by generating the
API for byref variable before API for its initializer. We will have this
test added to our internal test suite as a clang-style test is not possible
due to very convoluted IR sequence. Fixes radar 7745514.
