2012-10-16ARM ABI: fix ABI alignment issues when passing legal vector types as varargs.Manman Ren
We create an aligned temporary space and copy the content over from ap.cur to the temporary space. This is necessary if the natural alignment of the type is greater than the ABI alignment. rdar://12439123 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166040 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-16Implement GCC's -Wint-to-pointer-cast.David Blaikie
This implementation doesn't warn on anything that GCC doesn't warn on with the exception of templates specializations (GCC doesn't warn, Clang does). The specific skipped cases (boolean, constant expressions, enums) are open for debate/adjustment if anyone wants to demonstrate that GCC is being overly conservative here. The only really obvious false positive I found was in the Clang regression suite's MPI test - apparently MPI uses specific flag values in pointer constants. (eg: #define FOO (void*)~0) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166039 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-15[ms-inline asm] Rework the front-end to use the API introduced in r165946.Chad Rosier
-The front-end now builds a single assembly string and feeds it to the AsmParser. The front-end iterates on a per statement basis by calling the ParseStatement() function. Please note, the calling of ParseStatement() and and any notion of MCAsmParsedOperands will be sunk into the MC layer in the near future. I plan to expose more basic APIs such as getClobbers, etc. -The enumeration of the AsmString expressions have been reworked to use SMLocs rather than assembly Pieces, which were being parsed in the front-end. -The test case, t8(), was modified due to r129223. I'll have to find a way to work around things such as these. Sorry for the large commit, but breaking this in multiple smaller commits proved too irritating. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165957 91177308-0d34-0410-b5e6-96231b3b80d8

This was only used by OSAtomicChecker and makes it more difficult to update values for expressions that the environment may look through instead (it's not the same as IgnoreParens).

2012-10-13[analyzer] Remove unneeded 'inlineCall' checker callback.Jordan Rose
I believe the removed assert in CheckerManager says it best: InlineCall is a special hacky callback to allow intrusive evaluation of the call (which simulates inlining).
