Chris Lattner 7e8a99b1c3 fix PR8686, accepting a 'b' suffix at the end of all the setcc 
instructions.  I choose to handle this with an asmparser hack,
though it could be handled by changing all the instruction definitions
to allow be "setneb" instead of "setne".  The asm parser hack is
better in this case, because we want the disassembler to produce
setne, not setneb.

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.

 2010-11-24 21:57:39 +00:00

Bill Wendling 945b776b6e Add MC encodings for some Thumb instructions. Test for a few of them. The "bx 
lr" instruction cannot be tested just yet. It requires matching a "condition
code", but adding one of those makes things go south quickly...

llvm-svn: 119511
 2010-11-17 16:15:42 +00:00
Bill Wendling 9898ac97fd Proper encoding for VLDM and VSTM instructions. The register lists for these 
instructions have to distinguish between lists of single- and double-precision
registers in order for the ASM matcher to do a proper job. In all other
respects, a list of single- or double-precision registers are the same as a list
of GPR registers.

 2010-11-15 18:45:17 +00:00
Rafael Espindola 8c3039b67b Change MCExpr::EvaluateAsRelocatableImpl of variables to return the original 
variable if recursing fails to simplify it.

Factor AliasedSymbol to be a method of MCSymbol.

Update MCAssembler::EvaluateFixup to match the change in
EvaluateAsRelocatableImpl.

Remove the WeakRefExpr hack, as the object writer now sees the weakref with
no extra effort needed.

Nothing else is using MCTargetExpr, but keep it for now.

Now that the ELF writer sees relocations with aliases, handle

    .weak    foo2
foo2:
    .weak    bar2
    .set    bar2,foo2
    .quad    bar2

the same way gas does and produce a relocation with bar2.

llvm-svn: 119152
 2010-11-15 16:33:49 +00:00
Rafael Espindola 46c79ef113 Fix PR8565. 
This moves most of the isUsed logic to the MCSymbol itself. With this we
get a bit more relaxed about allowing definitions after uses: uses that
don't evaluate their argument immediately (jmp foo) are accepted.

ddunbar, this was the smallest compromise I could think of that lets us
accept gcc (and clang!) assembly.

llvm-svn: 119144
 2010-11-15 14:40:36 +00:00
Rafael Espindola 240028d11d Move the logic to decide with which symbol we produce a relocation (if any) to 
a central location. This also makes us a bit more compatible with gas.
