Bill Wendling 359dd0c6bd More tests to XFAIL. The arm-and-txt-peephole.ll test passes even when the 
peephole optimizer is disabled. That's not good at all.

Bill Wendling 7a23c1fb7d The testcase is now XFAILed. Sorry about the breakage.

Chris Lattner 1acd6b1edc "mov[zs]x (mem), GR16" are not ambiguous: the mem 
must be 8 bits.  Support this memory form.

Chris Lattner dd3b09c234 Implement enough of the missing instalias support to get 
aliases installed and working.  They now work when the
matched pattern and the result instruction have exactly
the same operand list.

This is now enough for us to define proper aliases for
movzx and movsx, implementing rdar://8017633 and PR7459.

Note that we do not accept instructions like:
  movzx 0(%rsp), %rsi

GAS accepts this instruction, but it doesn't make any
sense because we don't know the size of the memory
operand.  It could be 8/16/32 bits.

Chris Lattner ad77681253 rename InstructionInfo -> MatchableInfo since it now 
represents InstAliases as well.  Rename 
isAssemblerInstruction -> Validate since that is what
it does (modulo the ARM $lane hack).

 2010-11-01 05:06:45 +00:00
Chris Lattner ba465f9a8a refactor initialization of InstructionInfo to be sharable between 
instructions and InstAliases.  Start creating InstructionInfo's
for Aliases.

Chris Lattner 178f4bb62d make the asm matcher emitter reject instructions that have comments 
in their asmstring.  Fix the two x86 "NOREX" instructions that have them.
If these comments are important, the instlowering stuff can print them.

Sean Callanan 7c0962dc89 Fixed StackFrame::GetVariableList to add global 
variables to the list of found variables if they
have not yet been added.

 2010-11-01 04:38:59 +00:00
Chris Lattner 39bc53b33a refactor InstructionInfo to not have a pointer to CodeGenInstruction 
member, and make isAssemblerInstruction() a method (pushing some code
around inside it).

llvm-svn: 117895
 2010-11-01 04:34:44 +00:00
Chris Lattner 488c201bb7 define a new CodeGenInstAlias. It has an asmstring and operand list for now, 
todo: the result field.

 2010-11-01 04:05:41 +00:00
Chris Lattner d8adec70f3 factor the operand list (and related fields/operations) out of 
CodeGenInstruction into its own helper class.  No functionality change.

Chris Lattner f7a01e9f46 change the singleton register handling code to be based on Record*'s 
instead of strings, simplifying it.

 2010-11-01 01:47:07 +00:00
Chris Lattner b80ab36179 Give AsmMatcherInfo a CodeGenTarget, which simplifies a bunch of 
argument passing.  Consolidate all SingletonRegister detection
and handling into a new 
InstructionInfo::getSingletonRegisterForToken method instead of
having it scattered about.  No change in generated .inc files.

John McCall e6e622e789 Only apply -fvisibility-inlines-hidden to definitions. Apparently 
isInlined() just gives meaningless results for non-definitions.

Fixes rdar://problem/8614470

Chris Lattner 25d9c7fa2e move FlattenVariants out of AsmMatcherEmitter into a shared 
CodeGenInstruction::FlattenAsmStringVariants method.  Use it
to simplify the code in AsmWriterInst, which now no longer 
needs to worry about variants.

Chris Lattner 40dd3f0939 add a FIXME, $lane in ARM is an issue that needs to be resolved before 
this can start rejecting instructions.

Chris Lattner 941c19b7ba reject instructions that contain a \n in their asmstring. Mark 
various X86 and ARM instructions that are bitten by this as isCodeGenOnly,
as they are.

Chandler Carruth baa5126dbc Add a specialization for 'long', a hole in the set of fundamental 
specializations provided here. This is a little annoying because its size
changes from platform to platform. If possible, I may follow up with a patch
that uses standard constants to simplify much of this, but assuming for now
that was avoided for a reason.

Bill Wendling 0392f1b437 Disable the peephole optimizer until 186.crafty on armv6 is fixed. This is what 
looks like is happening:

Without the peephole optimizer:
  (1)   sub     r6, r6, #32
        orr     r12, r12, lr, lsl r9
        orr     r2, r2, r3, lsl r10
  (x)   cmp     r6, #0
        ldr     r9, LCPI2_10
        ldr     r10, LCPI2_11
  (2)   sub     r8, r8, #32
  (a)   movge   r12, lr, lsr r6
  (y)   cmp     r8, #0
LPC2_10:
        ldr     lr, [pc, r10]
  (b)   movge   r2, r3, lsr r8

With the peephole optimizer:
        ldr     r9, LCPI2_10
        ldr     r10, LCPI2_11
  (1*)  subs    r6, r6, #32
  (2*)  subs    r8, r8, #32
  (a*)  movge   r12, lr, lsr r6
  (b*)  movge   r2, r3, lsr r8

(1) is used by (x) for the conditional move at (a). (2) is used by (y) for the
conditional move at (b). After the peephole optimizer, these the flags resulting
from (1*) are ignored and only the flags from (2*) are considered for both
conditional moves.

Chris Lattner 7ff334687d fix the !eq operator in tblgen to return a bit instead of an int. 
Use this to make the X86 and ARM targets set isCodeGenOnly=1 
automatically for their instructions that have Format=Pseudo,
resolving a hack in tblgen.

Chris Lattner 9492c17baf two changes: make the asmmatcher generator ignore ARM pseudos properly, 
and make it a hard error for instructions to not have an asm string.
These instructions should be marked isCodeGenOnly.

 2010-10-31 19:05:32 +00:00
Chris Lattner 9293008e90 the asm matcher can't handle operands with modifiers (like ${foo:bar}). 
Instead of silently ignoring these instructions, emit a hard error and
force the target author to either refactor the target or mark the 
instruction 'isCodeGenOnly'.

Mark a few instructions in ARM and MBlaze as isCodeGenOnly the are 
doing this.
