 2012-06-04 02:39:52 +00:00
Hal Finkel 595817eebe Enable generating PPC pre-increment (r+imm) instructions by default. 
It seems that this no longer causes test suite failures on PPC64 (after r157159),
and often gives a performance benefit, so it can be enabled by default.

Douglas Gregor 5bee25884b When adding built-in operator candidates for overload resolution 
involving 'restrict', place restrict on the pointer type rather than
on the pointee type. Also make sure that we gather restrict from the
pointer type. Fixes PR12854 and the major part of PR11093.

Nico Weber cdfb1ae7f7 Improve fixit for comparison operator on lhs of bitwise operator. 
Before:

  if (0 == flags & 0xdd)
                 ^

 2012-06-02 18:20:16 +00:00
Argyrios Kyrtzidis 3c9aaf1ab8 Initialize the non-target-dependent fields of the Preprocessor in its constructor 
so we can destroy it even if it was constructed with "DelayInitialization = true",
and we didn't end up calling Preprocessor::Initialize.

Fixes crashes in rdar://11558355

Benjamin Kramer 172f80849f Use access(2) instead of stat(2) to check if a file exists. 
Apart from being slightly cheaper, this fixes a real bug that hits 32 bit
linux systems. When passing a file larger than 2G to be linked (which isn't
that uncommon with large projects such as WebKit), clang's driver checks
if the file exists but the file size doesn't fit in an off_t and stat(2)
fails with EOVERFLOW. Clang then says that the file doesn't exist instead
of passing it to the linker.

Simon Atanasyan 590ad8f515 MIPS: Factor out code selects the float ABI as determined by -msoft-float, 
-mhard-float, and -mfloat-abi= to the new function getMipsFloatABI. That
