This saves stack space in common cases and allows mem2reg in the caller. A simple example is: void foo(const Twine &); void bar(int x) { foo("xyz: " + Twine(x)); } Before: __Z3bari: subq $40, %rsp movl %edi, 36(%rsp) leaq L_.str3(%rip), %rax leaq 36(%rsp), %rcx leaq 8(%rsp), %rdi movq %rax, 8(%rsp) movq %rcx, 16(%rsp) movb $3, 24(%rsp) movb $7, 25(%rsp) callq __Z3fooRKN4llvm5TwineE addq $40, %rsp ret After: __Z3bari: subq $24, %rsp leaq L_.str3(%rip), %rax movq %rax, (%rsp) movslq %edi, %rax movq %rax, 8(%rsp) movb $3, 16(%rsp) movb $7, 17(%rsp) leaq (%rsp), %rdi callq __Z3fooRKN4llvm5TwineE addq $24, %rsp ret It saves 16 bytes of stack and one instruction in this case. llvm-svn: 103107

* Twines: Support numeric conversion directly (uitostr, etc).Daniel Dunbar2009-07-291-11/+37
| | | | | | | | | | | | | | | - Provides static constructors for doing number to string conversions without using temporaries. - There are several ways to do this, I think given the Twine constraints this is the simplest one. - One FIXME for fast number -> hex conversion. - Added another comment on one last major bit of perf work Twines need, which is to make raw_svector_ostream more efficient. llvm-svn: 77445
* Add Twine ADT.Daniel Dunbar2009-07-241-0/+91
