Bob Wilson 0106063556 Provide versions of the ARM eh_sjlj_setjmp instructions for non-VFP subtargets 
such that the non-VFP versions have no implicit defs of VFP registers.
If any callee-saved VFP registers are marked as having been defined, the
prologue/epilogue code will try to save and restore them.

Ted Kremenek 26984fb4eb Remove copy of 'Optional' in Clang tree, and convert clients to use the one now in the LLVM tree.

 2010-04-09 20:26:58 +00:00
Ted Kremenek 800b66be9d Remove fixit for string literal comparison. Telling the user to use 'strcmp' is bad, and 
we don't have enough information to tell them how to use 'strncmp'.  Instead, change the
diagnostic to indicate they should use 'strncmp'.

Chris Lattner 1ef9826ff8 "On SPU, variables in the .bss section that are allocated with the .lcomm directive are not aligned on 16 byte boundaries. This causes misaligned loads, as the generated assembly assumes this "default" alignment. 
this patch disables .lcomm in favour of '.local .comm'

Douglas Gregor fb8b27d530 Remove all "used" static functions *after* we have performed all of 
the implicit template instantiations we need to perform. Otherwise, we
end up erroneously diagnosing static functions as used if they were
only used within an implicit template instantiation. Fixes a bunch of
spurious failures when building Clang with Clang.

up adding the instruction to the wrong worklist,

Douglas Gregor c68e140657 Improve diagnostics when we fail to convert from a source type to a 
destination type for initialization, assignment, parameter-passing,
etc. The main issue fixed here is that we used rather confusing
wording for diagnostics such as

t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
      expected 'char *' [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:

t.c:2:9: warning: initializing 'char *' from an expression of type
      'char const [2]' discards qualifiers [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

Fixes <rdar://problem/7447179>.
