Dale Johannesen 0241bb57b2 When mixing SSE and x87 codegen, it's possible to 
have situations where an SSE instruction turns into
multiple blocks, with the live range of an x87
register crossing them.  To do this correctly make
sure we examine all blocks when inserting
FP_REG_KILL.  PR 1697.  (This was exposed by my
fix for PR 1681, but the same thing could happen
mixing x87 long double with SSE.)

Dan Gohman 1b2156fcae Add support on x86 for having Legalize lower ISD::LOCATION to ISD::DEBUG_LOC 
instead of ISD::LABEL with a manual .debug_line entry when the assembler
supports .file and .loc directives.

 2007-09-24 21:54:14 +00:00
Dan Gohman 3165699e4b Don't emit .debug_line header data if there aren't any lines to put in it, 
such as will happen when .loc directives are used.

Dan Gohman 9b00c07be5 Move the Asm->EOL() call for EmitDebugARanges outside the #ifdef for 
consistency with the other currently empty sections.

Dan Gohman 0baf84b2e1 Add support for emitting .file directives to set up file numbers for 
use with .loc directives.

Dan Gohman 0cc9d1b93b Merge hasDotLoc and hasDotFile into hasDotLocAndDotFile since .loc and .file 
aren't really usable without each other.

Daniel Berlin 5d7136a1df Implement offline variable substitution in order to reduce memory 
and time usage.
Fixup operator == to make this work, and add a resize method to DenseMap
so we can resize our hashtable once we know how big it should be.

Dan Gohman 6002818999 Use the correct result value type instead of using getValueType(0) 
in ExpandEXTRACT_VECTOR_ELT and SplitVectorOp. This fixes an abort
in the included testcase.

Chris Lattner 5b5484db63 claim that "st" is from the 80-bit register file. This causes x87-using inline 
asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.

Owen Anderson 15efb43db7 Factor the calculation details for PostDomTree out of PostDominators.cpp and 
into a separate header file.

Next step: merging PostDominatorCalculation.h with DominatorCalculation.h.

Owen Anderson da853a400f Move DFSPass back down into DominatorTree. I need to figure out what the difference is between it 
and the PostDomTree version first.

 2007-09-23 21:32:55 +00:00
Owen Anderson 84c357fc26 Factor the dominator tree calculation details out into DominatorCalculation.h. This 
change is not useful in and of itself, but it lays the groundwork for combining
the dominator and postdominator implementations.

Also, factor a few methods that are common to DominatorTree and PostDominatorTree
into DominatorTreeBase.  Again, this will make merging the two calculation methods
simpler in the future.

Dale Johannesen ae4bb05103 Implementation of +sse -sse2 has changed; add 
-sse to preserve intent of this test.

llvm-svn: 42247
 2007-09-23 14:58:14 +00:00
Dale Johannesen e36c400255 Fix PR 1681. When X86 target uses +sse -sse2, 
keep f32 in SSE registers and f64 in x87.  This
is effectively a new codegen mode.
Change addLegalFPImmediate to permit float and
double variants to do different things.
Adjust callers.

Gordon Henriksen 9af2d596ed Fix srcdir <> objdir builds with ocaml 2.10. Downrev versions don't care whether 
'dir' exists in 'ocamldep -I dir ...', but recent ones demand that it actually
exists.
