Jason W Kim 6c233c141e Fix two tiny issues (ARM does not need COFF) and comment sanity.

Benjamin Kramer 5d66e5feb8 Tighten up prototype verification of strchr and strrchr to avoid a crash in the very unlikely case that someone passes an integer > i64 to strchr.

Chandler Carruth f44d350614 Silence a GCC warning about not handling all flags in this switch, we 
specifically assert on unexpected flags.

Marcin Swiderski 99a9040a1f Added two new command line arguments: 
-cfg-add-implicit-dtors - sets CFG::BuildOptions::AddImplicitDtors for AnalysisCosumer to true,
-cfg-add-initializers - sets CFG::BuildOptions::AddInitializers for AnalysisCosumer to true.

Jan Wen Voung efbdbe5565 Move logic of determining ELF entsize from the .s printer to initialization 
time. That way, the EntrySize field is initialized for other code paths, 
namely, the .ll -> .o code path.

Rafael Espindola 70d6e0e0ff Correctly produce R_X86_64_32 or R_X86_64_32S. 
With this patch in

movq    $foo, foo(%rip)
foo:
.long   foo

We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the
second one.

Jason W Kim 645f6c2bef Tiny patch for proof-of-concept cleanup of ARMAsmPrinter::EmitStartOfAsmFile() 
Small test for sanity check of resulting ARM .s file.
Tested against -r115129.

Jan Wen Voung b96b2d8e4d Have ELFAsmParser.cpp use the already parsed "Size" (entry size) when 
constructing a section. Test for a few cases also included.

Rafael Espindola 2ebaee9c75 Make it possible for the MCObjectWriter to decide if a given fixup is fully 
resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.

Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.

Jim Grosbach 4a9cb8f10e Go ahead and jump! 
Now that the MC lowering handles the expansion of the pseudos, kill the horrible
blobs of text.

Jason W Kim b32124545b I added a new file ARMAsmBackend which stubs out in similar ways to 
the eqv X86 class.
For now, I split the ELFARMAsmBackend from the DarwinARMAsmBackend
(also mimicking X86)

Tested against -r115126

Jim Grosbach 2ff7de0264 Now that the pseudos that needed this are all custom lowered, we can go back 
to an empty PrintSpecial()

Jim Grosbach 080fdf4609 Nuke it from orbit. It's the only way to be sure. 
(Kill the dead non-MC asm printer for the ARM target.)

llvm-svn: 115127
 2010-09-30 01:57:53 +00:00
Jim Grosbach 4a57b76eea Let a target specify whether it wants an assembly printer to be the MC version 
or not. TableGen needs to generate the printInstruction() function as taking
an MCInstr* or a MachineInstr*, depending. Default to the old non-MC
version so that everything not yet using MC continues to just work without
fidding.

Johnny Chen 832d2333a5 Added a utility function to return the counterpart C++ compiler of $(CC) and use 
it inside Makefile.rules to return clang++ on clang and llvm-g++ on llvm-gcc.

Removed CPLUSPLUSFLAGS which is simply wrong and CPPFLAGS which is unnecessary.

Tom Care ea7c48ccf7 Updated scan-build: 
- Idempotent operations are on by default, to match --analyze in the driver.
- Integrated stats calculation based on parsing warnings emitted with the -analyzer-stats flag. The new -stats flag enables this.
- New -maxloop flag to pass down a maxloop value to the analyzer.

Evan Cheng 2fb20b1d37 ARM instruction itinerary fixes: 
1. Cortex-a9 8-bit and 16-bit loads / stores AGU cycles are 1 cycle longer than 32-bit ones.
2. Cortex-a9 is out-of-order so model all read cycles as cycle 1.
3. Lots of other random fixes for A8 and A9.

Ted Kremenek b0e7d77729 Include changes to VisitCXXMemberCallExpr (call visitor functions). 
llvm-svn: 115120
 2010-09-30 01:06:29 +00:00
Ted Kremenek e18dd0a84e Change CheckerVisitor so that [Pre,Post]VisitCallExpr only handles CallExprs for simple C functions, not 
all CallExprs (including CXXMemberCallExpr, etc.).  Now the generic handler for all CallExprs is [Pre,Post]VisitGenericCallExpr.

Also add [Pre,Post]Visit hooks for CXXMemberCallExpr.

Change GRExprEngine::VisitCXXMemberCallExpr() to do pre/post checker visits of the call.

Sebastian Redl 517523014d In MeasureTokenLength, the FileLoc supplied to the lexer must point to the start of the buffer, or we risk overflow.

Francois Pichet 083f368be1 Revert r114320(move file = copy + delete on Win32). r115040 is a better solution for the Win32 ACCESS_DENIED lit error.

 2010-09-29 23:52:12 +00:00
Tom Care 2f0419e1f8 AnalyzerStatsChecker improvements: 
- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable.
- Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing.

Tom Care a5f13c866c Modified the ccc-analyzer script to print the compiler command when log level verbosity is enabled. This is handy for debugging. 
llvm-svn: 115109
 2010-09-29 23:48:31 +00:00
Tom Care 472205be35 Change -analyzer-max-nodes to allow 0 as a parameter. This allows the analyzer to completely analyze a worklist regardless of time taken.

Owen Anderson 6d33f59952 Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also 
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.
