Anton Korobeynikov f16134141d Allow inline asm nodes with empty bodies inside JIT. 
This unbreaks explicit reg vars inside JIT, which are
implemented in such hacky way :)

Dan Gohman cdf1a276e3 getelementptr doesn't work on x86-64 yet, because it 
has MOV64ri32 and no plain MOV64ri.

Dan Gohman efb7d2d03d MVT::getMVT uses iPTR for pointer types, while we need the actual 
intptr_t type in this case. FastISel can now select simple
getelementptr instructions.

Dan Gohman 75ea0b83c5 Elements in DeadNodeSet are checked for use_empty() before they 
are actually deleted, so it's not necessary to remove re-used

Steve Naroff b2fc05227c RewriteObjC::RewriteObjCSynchronizedStmt(): Make sure the sync expr is cast to "id".

Owen Anderson 8bb9de9305 Implement operator<< in terms of basic types rather than [u]int*_t, which is better for portability. There might be some way to factor this all with metaprogramming magic, but I'm not sure how offhand.

Daniel Dunbar 66dd6382e4 Use full path to count script, and don't treat files with missing RUN 
lines as errors.

Daniel Dunbar 22d82ed0e2 Preliminary support for Obj-C classes in NeXT runtime. 
- Functional for simple cases but there are some glaring omissions
   (protocols, properties, and other language extensions).
 - The code needs a fair bit of cleaning.

Suppress count output from 'make test' on errors (used to generate
result code).

Eli Friedman a64e54d3f8 Remove size_t operator; this unbreaks the build on Linux. Committing on 
the suggestion of resistor.

If this breaks some other platform, please go ahead and back this out.

Daniel Dunbar 746d104b3d Reorder the PATH used during testing so $(ToolDir) and the LLVM 
scripts dir appear before the user path.
 - This is an attempt to pick up the right executables. We should
   probably be substituting the exact things we want for clang a la
   the LLVM test script.

Daniel Dunbar 19d84c3c51 Update a number of CodeGen tests to not create .ll files in the test 
directory.
 - Removed .ll from the svn:ignore lists to try and prevent this.
 - Added svn:ignore on test/Misc/Output

Dan Gohman fe9056584b Basic fast-isel support for instructions with constant int operands. 
llvm-svn: 55099
 2008-08-21 01:41:07 +00:00
Eli Friedman c968a6ab8e Initial implementation of Windows x86 target; at the moment, the only 
difference from generic x86 is the defines.  The rest is non-trivial to 
implement.

I'm not planning on adding any more targets myself; if there are any 
targets anyone is currently using that are missing, feel free to add 
them, or ask me to add them.

This concludes the work I'm planning for the TargetInfo 
implementations at the moment; all the other issues with TargetInfo require
some API changes, and I haven't really thought it through.  Some of the
remaining issues: allowing targets to define size_t and wchar_t properly,
adding some sort of __builtin_type_info intrinsic so we can finish clang's 
limits.h and float.h and get rid of a massive number of macro 
definitions, allowing target-specific command-line options, allowing
target-specific defaults for certain command-line options like
-fms-extensions, exposing vector alignment outside of the description 
string, exposing endianness outside of the description string, allowing 
targets to expose special bit-field layout requirements, exposing some 
sort of custom hook for call generation in CodeGen, and adding CPU 
selection to control defines like __SSE__.

Eli Friedman 873f65afe8 First cut at OS detection, taking advantage of the new generic targets. 
This approach allows adding OS-specific targets/defines/etc. without 
completely breaking unknown subtargets.  No new subtargets yet, although 
I plan to add x86-Linux soon.  Others can add targets that they use as 
needed; adding a new subtarget takes very little code.

Also does some fixups for description strings; a lot of them were 
unspecified.  I think all the ones I added are correct, but 
they're unverified; corrections are welcome.
