* Fall back to selection DAG isel for calls to builtin functions.Bob Wilson2012-08-031-3/+6
| | | | | | | | | | Fast isel doesn't currently have support for translating builtin function calls to target instructions. For embedded environments where the library functions are not available, this is a matter of correctness and not just optimization. Most of this patch is just arranging to make the TargetLibraryInfo available in fast isel. <rdar://problem/12008746> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161232 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix fastcc structure return with fast-isel on x86-32Derek Schuff2012-04-301-0/+2
| | | | | | | | | | | | | | | | On x86-32, structure return via sret lets the callee pop the hidden pointer argument off the stack, which the caller then re-pushes. However if the calling convention is fastcc, then a register is used instead, and the caller should not adjust the stack.

* Use the same CALL instructions for Windows as for everything else.Jakob Stoklund Olesen2012-02-161-6/+2
| | | | | | | The different calling conventions and call-preserved registers are represented with regmask operands that are added dynamically. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150708 91177308-0d34-0410-b5e6-96231b3b80d8
* Enable register mask operands for x86 calls.Jakob Stoklund Olesen2012-02-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Call instructions no longer have a list of 43 call-clobbered registers. Instead, they get a single register mask operand with a bit vector of call-preserved registers. This saves a lot of memory, 42 x 32 bytes = 1344 bytes per call instruction, and it speeds up building call instructions because those 43 imp-def operands no longer need to be added to use-def lists. (And removed and shifted and re-added for every explicit call operand). Passes like LiveVariables, LiveIntervals, RAGreedy, PEI, and BranchFolding are significantly faster because they can deal with call clobbers in bulk. Overall, clang -O2 is between 0% and 8% faster, uniformly distributed depending on call density in the compiled code. Debug builds using clang -O0 are 0% - 3% faster. I have verified that this patch doesn't change the assembly generated for the LLVM nightly test suite when building with -disable-copyprop and -disable-branch-fold. Branch folding behaves slightly differently in a few cases because call instructions have different hash values now. Copy propagation flushes its data structures when it crosses a register mask operand. This causes it to leave a few dead copies behind, on the order of 20 instruction across the entire nightly test suite, including SPEC. Fixing this properly would require the pass to use different data structures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150638 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up the handling of the x87 fp stack to make it more robust.Jakob Stoklund Olesen2011-06-281-7/+9
| | | | | | | | | | | | | | | | | | | | Drop the FpMov instructions, use plain COPY instead. Drop the FpSET/GET instruction for accessing fixed stack positions. Instead use normal COPY to/from ST registers around inline assembly, and provide a single new FpPOP_RETVAL instruction that can access the return value(s) from a call. This is still necessary since you cannot tell from the CALL instruction alone if it returns anything on the FP stack. Teach fast isel to use this. This provides a much more robust way of handling fixed stack registers - we can tolerate arbitrary FP stack instructions inserted around calls and inline assembly. Live range splitting could sometimes break x87 code by inserting spill code in unfortunate places. As a bonus we handle floating point inline assembly correctly now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134018 91177308-0d34-0410-b5e6-96231b3b80d8
