Bob Wilson 1905e2be86 Don't remove libLTO.dylib if it's not being installed in Developer/usr/lib; 
just leave it in Developer/usr/local/lib.

Duncan Sands 76d6217906 Verify metadata harder. In particular, check that module 
level metadata does not have any function local operands.
This would have caught the problem found in PR6112.

Torok Edwin 63dd86352e Fix PR6910. 
Limit alignment in SmallVector 8, otherwise GCC assumes 16 byte alignment.
opetaror new, and malloc only return 8-byte aligned memory on 32-bit Linux,
which cause a crash if code is compiled with -O3 (or -ftree-vectorize) and some
SmallVector code is vectorized.

Evan Cheng 38dfa5cf20 Load folding tail call should not use ebp / rbp after it's popped. PEI 
should use esp / rsp to reference frame instead.

Evan Cheng a5a8f76cea - Really preserve dbg_value instructions when the register is spilled. 
- Also, update dbg_value is the value is being re-matted from a frame slot, e.g. fixed slots for arguments.

Devang Patel bb728e17d3 tidy up. 
llvm-svn: 102558
 2010-04-28 23:24:13 +00:00
Kevin Enderby 4822841b82 Fixed the word sized Bit Scan Forward/Reverse instructions, they needed the 
Operand size override prefix to be part of their records.

Evan Cheng 6e822459ed Replace r102368 with code that's less fragile. This creates DBG_VALUE instructions for function arguments early and insert them after instruction selection is done.

be installed.  Disable it by default.

Devang Patel 4c18a3ac80 Update tests. Now DBG_VALUE instruction is created only if alloca corresponding to llvm.dbg.declare is missing.

Chris Lattner ee3576e8f1 declare targets with (void) instead of () since this is a C header. 
Patch by Lars R in PR6961.

llvm-svn: 102523
 2010-04-28 20:24:45 +00:00
Chris Lattner 450e29cb4c fix PR6112 - When globalopt (or any other pass) does RAUW(@G, %G), 
metadata references in non-function-local MDNodes should drop to 
null.

Evan Cheng d4d1a51895 Pretty print DBG_VALUE machine instructions. 
Before:
DBG_VALUE %RSI, 0, !-1; dbg:SimpleRegisterCoalescing.cpp:2707
Now:
DBG_VALUE %RSI, 0, !"this"; dbg:SimpleRegisterCoalescing.cpp:2707

Chris Lattner 08e9e72fa9 Rework global alignment computation again. Now we do round up 
alignment of globals to the preferred alignment, but only when
there is no section specified on the global (by far the common
case).

llvm-svn: 102515
 2010-04-28 19:58:07 +00:00
Devang Patel 888c17073a While lowering dbg_declare, emit DBG_VALUE machine instruction if alloca matching llvm.dbg.declare intrinsic is missing.

Jakob Stoklund Olesen 06e7242d32 Recompute kill flags from live intervals after coalescing instead of trying to 
update them. Computing kill flags is notoriously difficult, and the coalescer
would get it wrong sometimes, and it would completely skip physical registers.

Now we simply remove kill flags based on the live intervals after coalescing.
This is a few percent slower, but now we get correct kill flags for physical
registers after coalescing.

llvm-svn: 102510
 2010-04-28 18:28:39 +00:00
Jakob Stoklund Olesen 96fad31694 Teach X86FloatingPoint that a register can be killed multiple times by the same 
instruction.

This instruction would crash the pass:

  INLINEASM <es:foo $0 $1>, 9, %FP0<kill>, 9, %FP0<kill>, 14, %EFLAGS<earlyclobber,def,dead>

Now it doesn't.

Devang Patel 50c9431203 Emit debug info for byval parameters. 
llvm-svn: 102486
 2010-04-28 01:39:28 +00:00
Evan Cheng 347e3b8f15 Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).
