Richard Smith d7e1fe40e1 Teach __alignof__ to look through arrays before performing the
preferred-alignment transformations. Corrects alignof(T[]) to return
alignof(T) in all cases, as required by relevant standards.

Richard Smith f6d7030f0f Related to PR19992: when the GNU alignof-expression extension is applied to an
expression of array-of-unknown-bound type, don't try to complete the array
bound, and return the alignment of the element type rather than 1.

Reid Kleckner 377c1592f8 Recover from missing typenames on template args for MSVC compatibility
While matching a non-type template argument against a known template
type parameter we now modify the AST's TemplateArgumentLoc to assume the
user wrote typename.  Under -fms-compatibility, we downgrade our
diagnostic from an error to an extwarn.

Todd Fiala 712d1557a2 Fixed gdb-remote M test length parameter, added overwrite to test.
Initial check-in provided a nibble count instead of byte count for
the memory to write.  Fixed that.

Enhanced test to check for overwrite past the expected range of
writing to verify the correct amount is written.

2014-06-10 23:02:10 +00:00
Zachary Turner f6054ca18c Remove support for runtime multi-threading.
This patch removes the functions llvm_start_multithreaded() and
llvm_stop_multithreaded(), and changes llvm_is_multithreaded()
to return a constant value based on the value of the compile-time
definition LLVM_ENABLE_THREADS.

Previously, it was possible to have compile-time support for
threads on, and runtime support for threads off, in which case
certain mutexes were not allocated or ever acquired.  Now, if the
build is created with threads enabled, mutexes are always acquired.

A test before/after patch of compiling a very large TU showed no
noticeable performance impact of this change.

Ed Maste f57dcbb615 Remove duplicated code
We preivously had two copies of ::BytesAvailable with only trivial
differences between them, and fixes have been applied to only one of
them.

Instead of duplicating the whole function, hide the FD_SET differences
behind a macro.  This leaves only one small __APPLE__-specific #if
block, and fixes ^C on non-__APPLE__ platforms.

Tom Stellard 4e07b1d76b R600/SI: Emit an error when attempting to spill VGPRs v4
I can't get VGPR spilling to work reliable, so for now just emit
an error when the register allocator tries to spill VGPRs.

v2:
  - Fix build
v3:
  - Added crash fix when spilling SPGRs
v4:
  - Use V_MOV_B32 as a dummy instruction instead of S_NOP

Reid Kleckner b01961c2c1 Revert "Patch by Ray Donnelly to print register names instead of numbers."
This reverts commit r206683.

The code was confusing SEH register numbers with DWARF register numbers.
The test case it was committed with was obviously incorrect.  The
disassembler was roundtripping '.seh_pushreg %rsi' as '.seh_pushreg
%rbp', and other exciting things.

Noticed by Vadim Chugunov.
