Akira Hatanaka ae5a9d6578 Define classes ArithLogicR and ArithLogicOfR and make 32-bit and 64-bit 
arithmetic and logical instructions with three register operands derive from
them. Fix instruction encoding too.

Eric Christopher 498b7fd7fe Start handling debug line and scope information better: 
Migrate most of the location setting within the larger API in CGDebugInfo and
update a lot of callers.
Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
and replace it with DILexicalBlockFile usage.

Finishes off the rest of rdar://10246360

 2011-10-11 23:00:45 +00:00
Eric Christopher 6647b83087 Add a new wrapper node for a DILexicalBlock that encapsulates it and a 
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

Bill Wendling 579ff6c39c N.B. This is with the new EH scheme: 
The blocks with invokes have branches to the dispatch block, because that more
correctly models the behavior of the CFG. The dispatch of course has edges to
the landing pads. Those landing pads could contain invokes, which then have
branches back to the dispatch. This creates a loop. The machine LICM pass looks
at this loop and thinks it can hoist elements out of it. But because the
dispatch is an alternate entry point into the program, the hoisted instructions
won't be executed.

I wasn't able to get a testcase which was small and could reproduce all of the
time. The function_try_block.cpp in llvm-test was where this showed up.

Jim Grosbach 9398141c48 ARM assembly parsing and encoding for LDC{2}{L}/STC{2}{L} instructions. 
Fill out the rest of the encoding information, update to properly mark
the LDC/STC instructions as predicable while the LDC2/STC2 instructions are
not, and adjust the parser accordingly.

Cameron Zwarich 1a761dcfbd Fix PR11106 by correcting a typo that has been in the code for over a year. This 
would have never worked, since the element type of a vector type is never a
vector type. Also fix the conditional to be more direct in checking whether
EltTy is a vector type.

Jim Grosbach 12b2889989 ARM addressing mode cleanup for LDC/STC. 
We parse at least some forms of the instructions now. Encoding is
pretty screwed up, still, though.

unused) code from .cmake to DataTypes.h.in so that the files are essentially in
sync module differences in autoconf/cmake replacement syntax.

Daniel Dunbar 0f41eee2a0 Driver: Add support for a new -nostdlibinc option. 
- This disables the system include directories, but not the compiler builtin
   directories. Useful for projects that want to use things like the intrinsic
   headers, but are otherwise freestanding.

 - I'm willing to reconsider the option naming, I also considered providing an
   explicit -builtinc (which would match -nobuiltininc), but this is more
   consistent with existing options.

 2011-10-11 18:20:16 +00:00
Daniel Dunbar b25bfde52d Frontend: Replace -nostdinc by -nostdsysteminc (which is just system include 
paths). The -nostdinc behavior is now -nostdsysteminc + -nobuiltininc.
