Benjamin Kramer	87855d3013	Emit a better error when running out of registers on inline asm. ... The most likely case where this error happens is when the user specifies too many register operands. Don't make it look like an internal LLVM bug when we can see that the error is coming from an inline asm instruction. For other instructions we keep the "ran out of registers" error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192041 91177308-0d34-0410-b5e6-96231b3b80d8	2013-10-05 19:33:37 +00:00
Jakob Stoklund Olesen	6660ed5f2f	Don't run RAFast in the optimizing regalloc pipeline. ... The fast register allocator is not supposed to work in the optimizing pipeline. It doesn't make sense to compute live intervals, run full copy coalescing, and then run RAFast. Fast register allocation in the optimizing pipeline is better done by RABasic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158242 91177308-0d34-0410-b5e6-96231b3b80d8	2012-06-08 23:15:12 +00:00
Jakob Stoklund Olesen	9d812a2805	Better diagnostics when inline asm fails to allocate. ... asm.c:2:7: error: ran out of registers during register allocation asm(""::"r"(0), "r"(1), "r"(2), "r"(3), "r"(4), "r"(5), "r"(6), "r"(7), "r"(8), "r"(9)); ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134310 91177308-0d34-0410-b5e6-96231b3b80d8	2011-07-02 07:17:37 +00:00
Jakob Stoklund Olesen	bf4e10f2f6	Emit a proper error message when register allocators run out of registers. ... This can't be just an assertion, users can always write impossible inline assembly. Such an assembly statement should be included in the error message. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131024 91177308-0d34-0410-b5e6-96231b3b80d8	2011-05-06 21:58:30 +00:00
