2012-10-18 17:51:43 +00:00
Chad Rosier ce2bcbf8c0 [ms-inline asm] Move most of the AsmParsing logic in clang back into the MC
layer.  Use the new ParseMSInlineAsm() API and add an implementation of the
MCAsmParserSemaCallback interface.

llvm-svn: 166184
2012-10-18 15:49:40 +00:00
Chad Rosier 4a0054f383 [ms-inline asm] Rework the front-end to use the API introduced in r165946.
-The front-end now builds a single assembly string and feeds it to the
 AsmParser.  The front-end iterates on a per statement basis by calling the
 ParseStatement() function.  Please note, the calling of ParseStatement() and
 and any notion of MCAsmParsedOperands will be sunk into the MC layer in the
 near future.  I plan to expose more basic APIs such as getClobbers, etc.

-The enumeration of the AsmString expressions have been reworked to use SMLocs
 rather than assembly Pieces, which were being parsed in the front-end.

-The test case, t8(), was modified due to r129223.  I'll have to find a way to
 work around things such as these.

Sorry for the large commit, but breaking this in multiple smaller commits proved
too irritating.

Chad Rosier e66f42634f [ms-inline asm] Lookup the IdentifierInfo using the Idents table and remove the
now unused static helper function.

The test case needs to be remove temporarily until I can better filter memory
operands that aren't actual variable reference.

Chad Rosier b261a50b40 [ms-inline asm] Handle the enumeration of input and output expressions in a
more robust way to address a few FIXMEs.

The initial implementation, r163342, built the IR asm string and then tried to
patch things on the fly without enough context.  Specifically, it didn't skip
mnemonics nor did it track with assembly instruction an expression was related
to.  The new implementation patches the operands and then builds the final
IR string.

Chad Rosier 57cd91f683 [ms-inline asm] If we have a single asm operand that maps to multiple
MCOperands then iterate over all of then when computing clobbers, inputs and
outputs.

On x86 the 1-to-many mapping is a memory operand that includes a BaseReg(reg),
MemScale(imm), MemIndexReg(reg), an Expr(MCExpr or imm) and a MemSegReg(reg).
Invalid register (Op.getReg() == 0) are not considered when computing clobber.

Chad Rosier c05d2c908d [ms-inline asm] The IR representation of inline assembly enumerates the input

Chad Rosier dea7964ddb [ms-inline asm] The MCInstrDesc only tracks register definitions. For now,
assume that if the 1st operands is an expression and the instruction mayStore,
then it is a memory definition.

Chad Rosier d997bd1422 [ms-inline asm] Start sending non-simple inline asms to the AsmParser.

Chad Rosier 3d4b98b4bc [ms-inline asm] Add a helper function, isMSAsmKeyword().
These require special handling, which we don't currently handle.  This is being
put in place to ensure we don't do invalid symbol table lookups or try to parse
invalid assembly.  The test cases just makes sure the latter isn't happening.

Chad Rosier 592b90a476 [ms-inline asm] Start tracking which tokens are registers and which are
variables, function or label references.  The former is a potential clobber.
The latter is either an input or an output.  Unfortunately, it's difficult to
test this patch at the moment, but the added test case will eventually do so.

Chad Rosier aa7c1cb5f8 [ms-inline asm] MSVC parses multiple __asm statements on a single line as one
statement.  For example,

  if (x)
    __asm out dx, ax  __asm out dx, ax

results in a single inline asm statement (i.e., both "out dx, ax" statements are
predicated on if(x)).

2012-08-14 19:22:06 +00:00
Chad Rosier 65a8e0b69f [ms-inline asm] Have patchMSAsmStrings() return a vector or AsmStrings.
The AsmParser expects a single asm instruction, but valid ms-style inline asm
statements may contain  multiple instructions.

This happens with asm blocks

__asm {
  mov ebx, eax
  mov ecx, ebx
}

or when multiple asm statements are adjacent to one another

__asm mov ebx, eax
__asm mov ecx, ebx

and

__asm mov ebx, eax __asm mov ecx, ebx

Currently, asm blocks are not properly handled.
