Dan Gohman e6d40166a8 Transfer debug location information from PHI nodes to resulting
lowered copies.

Dan Gohman 7421ae48bf Disable the new unknown-location code for now. It causes a major
increase in the debug line info section, and it's causing
regressions in a gdb testsuite.

Evan Cheng ddc93c7e04 Remove VLD1q and VST1q for reloading and spilling Q registers. Just use VLD1q64 / VST1q64 and reference sub-registers.

mike-m c750e87c33 Disable man->postscript and man->pdf doc generation unless explicitly
configured via --enable-doxygen. It seems some systems have broken pdfroff
so automatic use of it is not safe.

mike-m 90fbedcb54 Cleanup unneeded dirs after docs overhaul.
llvm-svn: 103215
2010-05-06 23:48:37 +00:00
mike-m e08af303a6 Overhauled llvm/clang docs builds. Closes PR6613.
NOTE: 2nd part changeset for cfe trunk to follow.

*** PRE-PATCH ISSUES ADDRESSED

- clang api docs fail build from objdir
- clang/llvm api docs collide in install PREFIX/
- clang/llvm main docs collide in install
- clang/llvm main docs have full of hard coded destination
  assumptions and make use of absolute root in static html files;
  namely CommandGuide tools hard codes a website destination
  for cross references and some html cross references assume
  website root paths

*** IMPROVEMENTS

- bumped Doxygen from 1.4.x -> 1.6.3
- splits llvm/clang docs into 'main' and 'api' (doxygen) build trees
- provide consistent, reliable doc builds for both main+api docs
- support buid vs. install vs. website intentions
- support objdir builds
- document targets with 'make help'
- correct clean and uninstall operations
- use recursive dir delete only where absolutely necessary
- added call function fn.RMRF which safeguards against botched 'rm -rf';
  if any target (or any variable is evaluated) which attempts
  to remove any dirs which match a hard-coded 'safelist', a verbose
  error will be printed and make will error-stop.

Daniel Dunbar 21aa523c28 MC/X86: X86AbsMemAsmOperand is subclass of X86NoSegMemAsmOperand.

Sean Callanan e7e1cf9fbd Eliminated the classification of control registers into %ecr_
and %rcr_, leaving just %cr_ which is what people expect.
Updated the disassembler to support this unified register set.
Added a testcase to verify that the registers continue to be
decoded correctly.

Bob Wilson 0e0f99816a Fix handling of unreachable blocks in the SSAUpdater. The previous code only
handled cases where a block had zero predecessors, but failed to detect other
cases like loops with no entries.  The SSAUpdater is already doing a forward
traversal through the blocks, so it is not hard to identify the blocks that
were never reached on that traversal.  This fixes the crash for ppc on the
stepanov_vector test.

Daniel Dunbar b0ceb764b8 Revert r103137, fix for $ in labels. It looks like we can't actually handle this
at the token level. Consider the following horrible test case:

  a = 1
  .globl $a
  movl ($a), %eax
  movl $a, %eax
  movl $$a, %eax

Evan Cheng 31cdcd46d6 Re-apply 103156 and 103157. 103156 didn't break anything. 10315 exposed a coalescer bug that's fixed by 103170.
llvm-svn: 103172
2010-05-06 06:36:08 +00:00
Evan Cheng c0255bac1d Fixes a coalescer bug that caused llc to crash on 2009-11-30-LiveVariablesBug.ll
with the fix in 103157.

%reg1039:1<def> = VMOVS %S1<kill>, pred:14, pred:%reg0
is not coalescable since none of the super-registers of S1 are in reg1039's
register class: DPR_VFP2. But it is still a legal copy instruction so it should
not assert.
