Venkatraman Govindaraju dc3bcc19cf [SparcV9] Add support for JIT in Sparc64. 
With this change, all supported tests in test/ExecutionEngine pass in sparcv9.

llvm-svn: 199977
 2014-01-24 07:10:19 +00:00
Jakob Stoklund Olesen 05ae2d6715 Implement atomicrmw operations in 32 and 64 bits for SPARCv9. 
These all use the compare-and-swap CASA/CASXA instructions.

Venkatraman Govindaraju 407e442245 [Sparc] Add support for inline assembly constraint 'I'.

Lang Hames 06234ec147 Add FPExt option to CCValAssign::LocInfo. When generating calling-convention 
promotion code, Tablegen will now select FPExt for floating point promotions
(previously it had returned AExt, which is not valid for floating point types).

Any out-of-tree targets that were relying on AExt being returned for FP
promotions will need to update their code check for FPExt instead.

Jakob Stoklund Olesen e7084a1c5c The SPARCv9 ABI returns a float in %f0. 
This is different from the argument passing convention which puts the
first float argument in %f1.

With this patch, all returned floats are treated as if the 'inreg' flag
were set. This means multiple float return values get packed in %f0,
%f1, %f2, ...

Note that when returning a struct in registers, clang will set the
'inreg' flag on the return value, so that behavior is unchanged. This
also happens when returning a float _Complex.

Chandler Carruth 8a8cd2bab9 Re-sort all of the includes with ./utils/sort_includes.py so that 
subsequent changes are easier to review. About to fix some layering
issues, and wanted to separate out the necessary churn.

Also comment and sink the include of "Windows.h" in three .inc files to
match the usage in Memory.inc.

Bill Wendling 908bf814e7 Refactor function that checks that __builtin_returnaddress's argument is constant. 
This moves the check up into the parent class so that all targets can use it
without having to copy (and keep in sync) the same error message.

llvm-svn: 198579
 2014-01-06 00:43:20 +00:00
Bill Wendling df7dd28dc8 Emit an error message if the value passed to __builtin_returnaddress isn't a constant 
__builtin_returnaddress requires that the value passed into is be a constant.
However, at -O0 even a constant expression may not be converted to a constant.
Emit an error message intead of crashing.

Venkatraman Govindaraju 55ecb10e99 [Sparc] Correctly handle call to functions with ReturnsTwice attribute. 
In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores
the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7)
using the stored %fp and register windows. However, this does not guarantee that the longjmp
will restore the registers, as they were when the setjmp was called. This is because these
registers may be clobbered after returning from setjmp, but before calling longjmp.

This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask.
