Reid Spencer 309080abbc Fix PR902: 
Errors are generated with the YYERROR macro which can only be called from
a production (inside yyparse) because of the goto statement in the macro.
This lead to several situations where GEN_ERROR was not called but
GenerateError was used instead (because it doesn't use YYERROR). However,
in such situations, catching the error much later (e.g. at the end of
the production) is not sufficient because LLVM can assert on invalid data
before the end of the production is reached. The solution is to ensure that
the CHECK_FOR_ERROR macro (which invokes YYERROR if there's an error) is
used as soon as possible after a call to GenerateError has been made.

Bill Wendling 5d409822d6 "Once more into the breach, dear friends, once more, or fill the wall up 
with our English dead."

No! Really! Serious this time...It was how the vreg uses were being
adjusted that was causing hte Olden tests to fail. I corrected this and
the Olden and Regression tests all passed.

Evan Cheng d31f55c236 PEI now place callee save spills closest to the address pointed to by the 
incoming stack. This allows X86 backend to use push / pop in epilogue /
prologue.

llvm-svn: 30636
 2006-09-28 00:10:27 +00:00
Evan Cheng 17a8d08dba - Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI just 
before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.
- Modified comments. It's important to note the order of registers in the array
returns by getCalleeSaveRegs() determines the order of callee save spill code.

Chris Lattner 5d751b4a3a This: 
AggregateString += "\0\0";

Doesn't add two nuls to the AggregateString (for obvious reasons), which
broke the asmprinter when the first character of an asm string was not
literal text.

Bill Wendling 0a7f617a6c PR878: Instead of calculating the vreg to PHI use count everytime we get 
a function, do it up front in linear time (going through all of the
instructions once). We create a map out of them. Then it's no problem to
use the information in it during elimination...

llvm-svn: 30618
 2006-09-26 23:47:10 +00:00
Chris Lattner 5fd0154523 Add support for ${:foo} syntax, where "foo" is passed into "printSpecial" and 
has no associated operand.  This is useful for portably encoding stuff like
the comment character into an asm string.
