John McCall 5b0829a321 Improve access control diagnostics. Perform access control on member-pointer 
conversions.  Fix an access-control bug where privileges were not considered
at intermediate points along the inheritance path.  Prepare for friends.

Daniel Dunbar f22553a1c7 MC/AsmMatcher: Add support for creating tied operands when constructing MCInsts. 
- Pretty messy, but we need to rework how we handle tied operands in MCInst
   anyway.

same length.

Daniel Dunbar 605474463f MC: Switch MCFixup to just hold an MCExpr pointer instead of index into the 
MCInst it came from.

Sean Callanan 7b0c339510 Updated the enhanced disassembly library's TableGen 
backend to not use exceptions at all except in cases
of actual error.

Sean Callanan e9959a5f1a Updated the TableGen emitter for the Enhanced 
Disassembler to take advantage of the refactored
AsmWriterInst.h.  Note removed parser code.

llvm-svn: 95760
 2010-02-10 02:47:08 +00:00
Sean Callanan 515937d2ea Changed AsmWriterOperand to also include the index of the 
operand into the CodeGenInstruction's list of operands,
which is useful for EDEmitter.  (Still working on PR6219)

Evan Cheng 29b8f554fc Now that ShrinkDemandedOps() is separated out from DAG combine. It sometimes leave some obvious nops which dag combine used to clean up afterwards e.g. (trunk (ext n)) -> n. Look for them and squash them.

Chris Lattner a9dfb1bc07 Introduce a new CodeGenInstruction::ConstraintInfo class 
for representing constraint info semantically instead of
as a c expression that will be blatted out to the .inc
file.  Fix X86RecognizableInstr to use this instead of
parsing C code :).

Also, fix a silly memory leak.

Dale Johannesen f8f9f55468 Skip DBG_VALUE many places in live intervals and 
register coalescing.  This fixes many crashes and
places where debug info affects codegen (when
dbg.value is lowered to machine instructions, which
it isn't yet in TOT).

Chris Lattner 74e6852510 Move verbose asm instruction comments to using MCStreamer. 
The major win of this is that the code is simpler and they 
print on the same line as the instruction again:

        movl    %eax, 96(%esp)          ## 4-byte Spill
        movl    96(%esp), %eax          ## 4-byte Reload
        cmpl    92(%esp), %eax          ## 4-byte Folded Reload

Dale Johannesen d40d42c9e5 Add isDebug argument to ChangeToRegister; this prevents 
the field from being used uninitialized later in some cases.

 2010-02-10 00:41:49 +00:00
Chris Lattner ff68a42121 print all the newlines at the end of instructions with 
OutStreamer.AddBlankLine instead of textually.

Fariborz Jahanian 113b8ad7cf Reverse a partial fix patch for radar 7214820. It broke some code and 
I don't have time to refix it for now.

Douglas Gregor 811663eb11 Implement basic support for importing source locations from one AST 
into another AST, including their include history. Here's an example
error that involves a conflict merging a variable with different types
in two translation units (diagnosed in the third AST context into
which everything is merged).

/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var2.c:3:5:
error: external variable 'x2' declared with incompatible types in
different translation units ('int' vs. 'double')
int x2;
    ^

/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.h:1:8:
note: declared here with type 'double'
double x2;
       ^

Although we maintain include history, we do not maintain macro
instantiation history across a merge. Instead, we map down to the
spelling location (for now!).

prefix which is part of the opcode encoding.

Chris Lattner 482bf69bfe Add ability for MCInstPrinters to add comments for instructions. 
Enhance the x86 backend to show the hex values of immediates in
comments when they are large.  For example:

        movl    $1072693248, 4(%esp)    ## imm = 0x3FF00000

David Greene 509be1fe5e TableGen fragment refactoring. 
Move some utility TableGen defs, classes, etc. into a common file so
they may be used my multiple pattern files.  We will use this for
the AVX specification to help with the transition from the current
SSE specification.
