Anna Zaks fedf5dfc71 [analyzer] Warn about the use of insecure, deprecated vfork() function PR11053 (http://llvm.org/bugs/show_bug.cgi?id=11053). 
A patch by Graham Lee!

Craig Topper a697852386 Fix disassembling of popcntw. Also remove some code that says it accounts for 64BIT_REXW_XD not existing, but it does exist.

Nick Lewycky 29e7b315ac Also create a shndx even if there are no symbols. This lets us test 
.symtab_shndx reading and writing together, and finally we have a testcase for
r141440.

NAKAMURA Takumi ba38717f34 test/CodeGen/X86/movbe.ll: Give explicit -mtriple=x86_64-linux, to unbreak win32 hosts.

Nick Lewycky 43f01cae95 Reapply r141605 with fixes for appropriate handling of reserved section numbers 
in st_shndx fields.

 2011-10-11 03:12:01 +00:00
Nick Lewycky 7adc4370e0 Add support for .symtab_shnidx. Unfortunately, doing this required breaking a 
layer of abstraction around SymbolRef where you can read its private
SymbolPimpl member.

Andrew Trick ecbe22bb8d Add experimental -enable-lsr-phielim option. 
I'm not sure we will need it in the long run, but the option is
currently useful for checking if the output of LSR is "clean".

Andrew Trick f9201c572e Move replaceCongruentIVs into SCEVExapander and bias toward "expanded" 
IVs.

Indvars previously chose randomly between congruent IVs. Now it will
bias the decision toward IVs that SCEVExpander likes to create. This
was not done to fix any problem, it's just a welcome side effect of
factoring code.

 2011-10-11 01:30:59 +00:00
Johnny Chen 999f7ab9bd Add '-k' option to the test driver to be able to specify a runhook, which is an lldb command 
for the debugger to execute for certain kind of tests (for example, a benchmark).
A list of runhooks can be used to steer the debugger into the desired state before more
actions can be performed.

type mask.

Jim Ingham ea8005a786 Fix a couple of places in FindFunctions where I was using the passed in name_type_mask 
rather than the computed effective_name_type_mask.

Akira Hatanaka b6d72cbeb9 Make changes necessary for supporting floating point load and store instructions 
that have 64-bit pointers or access the 32 x 64-bit floating pointer register
file. Update functions in MipsInstrInfo.cpp too.

Kaelyn Uhrain 85308c6ecd Add typo correction for type names. 
The main motivation was to do typo correction in C++ "new" statements,
though picking it up in other places where type names are expected was
pretty much a freebie.

Ted Kremenek 03eec60483 Place diagnostic group ext_typecheck_decl_incomplete_type under a -W flag.

 2011-10-11 01:02:24 +00:00
Jakob Stoklund Olesen da7c0f8f7d Move -widen-vmovs to ARMBaseInstrInfo::expandPostRAPseudo(). 
The VMOVS widening needs to look at the implicit COPY operands.  Trying
to dig out the COPY instruction from an iterator in copyPhysReg() is the
wrong approach.

The expandPostRAPseudo() hook gets to look at COPY instructions before
they are converted to copyPhysReg() calls.

Akira Hatanaka 09b23eb7bc Modify lowering of GlobalAddress so that correct code is emitted when target is 
Mips64.

Akira Hatanaka be68f3c348 Add definitions of 64-bit loads and stores. Add a patterns for unaligned 
zextloadi32 for which there is no corresponding pseudo or real instruction.

Tanya Lattner cbb9140806 Make it possible to use the linker without destroying the source module. This is so the source module can be linked to multiple other destination modules. For all that used LinkModules() before, they will continue to destroy the source module as before. 
This line, and those below, will be ignored--

Nick Lewycky fdbb7c51e9 Add support for reading many-section ELF files. 
If you want to tackle adding the testcase, let me know. It's a 4.2MB ELF file
and I'll be happy to mail it to you.

Akira Hatanaka fd2d7dcc31 Change definitions of classes LoadM and StoreM in preparation for adding support 
for 64-bit load and store instructions. Add definitions of 64-bit memory operand

Lang Hames 60b2b2ee0d Update target data strings for ARM and X86 to include the natural stack 
alignment parameter "S<size>" that was introduced in r141599.

llvm-svn: 141601
 2011-10-10 23:44:43 +00:00
Douglas Gregor 2259d85a43 Don't crash in Sema::IsSimplyAccessible if the declaration is not a C++ class member. Fixes PR11108. 
llvm-svn: 141600
 2011-10-10 23:44:35 +00:00
Lang Hames de7ab801cc Add a natural stack alignment field to TargetData, and prevent InstCombine from 
promoting allocas to preferred alignments that exceed the natural
alignment. This avoids some potentially expensive dynamic stack realignments.

The natural stack alignment is set in target data strings via the "S<size>"
option. Size is in bits and must be a multiple of 8. The natural stack alignment
defaults to "unspecified" (represented by a zero value), and the "unspecified"
value does not prevent any alignment promotions. Target maintainers that care
about avoiding promotions should explicitly add the "S<size>" option to their
target data strings.

Douglas Gregor e442fe3db9 Make sure we initialize the "extra" data within the libclang code 
completion context, in case we end up having no code-completion
callback. Individual instances of this problem are always bugs that
need to be fixed, but it's better to make sure we have initialized
data here.

Johnny Chen 541b98517e Remove test logic to check for clang and skip the rest due to insufficient debug info. 
Recent changes in lldb inlining robustness seem to have fixed it.
