This component is still at an early stage, but allows for simple
breakpoint/step-over operations and basic process control.

The makefiles are set up to build the plugin under Linux only.

spurious guard variables on expression statics.

Updated the AST result synthesizer to eliminate the
unneeded result pointer.

Very rudimentary expressions now evaluate correctly
in the target using the new JIT-based mechanism.

when the RHS of the ||/&& is ever 0 or 1.  This handles a variety of
creative idioms for "true" used in C programs and fixes many false 
positives at the expense of a few false negatives.  This fixes
rdar://8230351.

Untangle filename/dirname confusion. Store constructed strings on the side. Avoid use of Path.makeAbsolute().

DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are:

$ clang foo.c -g
  DW_AT_name - foo.c
  DW_AT_comp_dir - `pwd`

$ clang one/two/foo.c -g
  DW_AT_name - one/two/foo.c
  DW_AT_comp_dir - `pwd`

$ clang /tmp/one/foo.c -g
  DW_AT_name - /tmp/one/foo.c
  DW_AT_comp_dir - empty

llvm-svn: 109303

Use current working directory when Dirname is empty. This only happens when absolute source file path is used on compiler command line.

precompiled preamble. This will suppress the -pedantic "no newline at
end of file" warning.

appropriate for targets without detailed instruction iterineries.
The scheduler schedules for increased instruction level parallelism in
low register pressure situation; it schedules to reduce register pressure
when the register pressure becomes high.

On x86_64, this is a win for all tests in CFP2000. It also sped up 256.bzip2
by 16%.

appropriately-padded main file buffer (that has spaces in the extra
"reserved" space) and thread that buffer through to the parsing
function. This still does nothing.

llvm-svn: 109299

Diagnose attempts to do this under the GNU or fragile NeXT runtimes.

llvm-svn: 109298

use of property-dot syntax using 'super' as receiver
is 'void'. This fixes a bug in generating correct
API for setter call. Fixes radar 8203426.

Sema::ActOnDeclarator doesn't mean that the Decl we ended up creating
has a useful name. <rdar://problem/8229910>

that preamble (the preamble text, preamble file, reserved main file
size). Check these details when we try to rebuild the precompiled
preamble, and when nothing has changed, re-use the precompiled
preamble.

This code is still very much a WIP, and can't even properly be tested
because we have no way to use the precompiled preamble yet. "Trust me"

function live in set. This will give us tGPR for Thumb1 and GPR otherwise,
so the copy will be spillable. rdar://8224931

to be of a different register class. For example, in Thumb1 if the live-in is
a high register, we want the vreg to be a low register. rdar://8224931

  SBTarget:
    - get breakpoint count
    - get breakpoint at index
  SBBreakpoint:
    - Extract data from breakpoint events

llvm-svn: 109289

llvm-svn: 109288

- Created a new class to do post-analysis
- Updated several test cases with unreachable code to expect a warning
- Added some general tests

comments explaining why it was wrong.  8225024.

Fix the real problem in 8213383: the code that splits very large
blocks when no other place to put constants can be found was not
considering the case that the block contained a Thumb tablejump.

  it's too late to start backing off aggressive latency scheduling when most
  of the registers are in use so the threshold should be a bit tighter.
- Correctly handle live out's and extract_subreg etc.
- Enable register pressure aware scheduling by default for hybrid scheduler.
  For ARM, this is almost always a win on # of instructions. It's runtime
  neutral for most of the tests. But for some kernels with high register
  pressure it can be a huge win. e.g. 464.h264ref reduced number of spills by
  54 and sped up by 20%.

llvm-svn: 109279

- When we JIT an expression, we print the disassembly
  of the generated code
- When we put the structure into the target, we print
  the individual entries in the structure byte for
  byte.
