llvm-svn: 54486

Fixed bug in adjustMipsStackFrame, which was breaking
while trying to access a dead stack object index. Also added
one more alignment before fixing the callee saved registers
stack offset adjustment.

FPROUND_F80_F32, FPROUND_PPCF128_F32, 
FPROUND_F80_F64, FPROUND_PPCF128_F64

Support for soften float fp_round operands is added, Mips 
needs this to round f64->f32.

Also added support to soften float FABS result, Mips doesn't 
support double fabs results while in 'single float only' mode.

llvm-svn: 54484

Do a dominator walk when scheduling copies, rather than a DFS on the CFG.  Also, fix a few problems when creating
live intervals for temporaries created by phi elimination.

and objc++.

llvm-svn: 54474

Fix by Jordan Breeding: when scanning for prior runs, scan-build should ignore files that are not directories.

llvm-svn: 54473

Fix --html-diags in driver by delaying the construction of an HTMLDiagnosticClient until after we have created the Preprocessor object.

directory: some people (guess who!) may build llvm-gcc
with support for objc but not with support for objc++.

LowerSubregs, and fix an x86-64 isel bug that this exposed.

SUBREG_TO_REG for x86-64 implicit zero extension is only safe for
isel to generate when the source is known to always have zeros in
the high 32 bits. The EXTRACT_SUBREG instruction does not clear
the high 32 bits.

are allocated in the same buffer as the code,
jump tables, etc.

The default JIT memory manager does not handle buffer
overflow well.  I didn't introduce this and I'm not
attempting to fix it here, but it is more likely to
be hit now since we're putting more stuff in the
buffer.  This affects one test that I know of so far,
MultiSource/Benchmarks/NPB-serial/is.

Unify logic in return-of-stack-check (Sema) for casts and implicit casts.
