Rafael Espindola 7a6e441262 Move a bit of duplicated code into a helper function.
llvm-svn: 168533
2012-11-24 02:18:49 +00:00
Rafael Espindola 1c3086cc91 Refactor how MCCFIInstructions are created.
Give MCCFIInstruction a single, private constructor and add helper static
methods that create each type of cfi instruction. This is is preparation
for changing its representation. The representation with a pair
MachineLocations older than MC and has been abused quiet a bit to support
more cfi instructions.

Benjamin Kramer 455fa35e51 CodeGenPrepare: Move ret duplication out of the instruction iteration loop.
It can delete the block, and the loop continues on free'd memory.
No change in output. Found by valgrind.

Daniel Malea a35970a6f6 Fix Linux bug that leaves lldb in invalid state after expression evaluation times out.
- Handle EINVAL return code from ptrace(GETSIGINFO, ...): not an error, but 'group-stop' state on Linux
- propagate SIGSTOP to inferior in above case
- this commit resolves the failure in expression_command/timeout testcase

Thanks to Sean Callanan & Matt Kopec for helping debug this problem

Rafael Espindola b3b60570e3 Add a -disable-cfi option to llvm-mc. This is useful for debugging as
it will expand any .cfi_* directives in the input assembly.

Unfortunately this cannot replace elf-dump in tests as the asm streamer
cannot relax the line advance opcodes.

Decl::isUsed checks the attribute. If the function had a body just the check

Bob Wilson decc03efe8 Reapply a subset of r167567 to clean up Darwin-specific code for invoking gcc.
Unlike my previous attempt at this, this patch leaves intact the check for
whether clang can handle the input file type, and for non-Darwin toolchains it
will invoke gcc for things it cannot handle. For Darwin toolchains, the
behavior reported in pr14338 still occurs with this patch, but that is a
definite improvement from what happens currently, where it just crashes with
an assertion failure.

Preston Briggs 3ad394931d Corrects a problem where we reply exclusively of GEPs to drive
analysis.  Better is to look for cases with useful GEPs and use them
when possible.  When a pair of useful GEPs is not available, use the
raw SCEVs directly. This approach supports better analysis of pointer
dereferencing.

In parallel, all the test cases are updated appropriately.
Cases where we have a store to *B++ can now be analyzed!

Chandler Carruth 05fb585a36 Fix the '-fuse-init-array' option to actually be an option.
Previously, this flag to CC1 was never exposed at the clang driver
layer, and if you happened to enable it (by being on Android or GCC 4.7
platform), you couldn't *disable* it, because there was no 'no' variant.
The whole thing was confusingly implemented.

Now, the target-specific flag processing gets the driver arg list, and
we use standard hasFlag with a default based on the GCC version and/or
Android platform. The user can still pass the 'no-' variant to forcibly
disable the flag, or pass the positive variant to clang itself to enable
the flag.

The test has also been substantially cleaned up and extended to cover
these use cases.
