2006-05-24For PR786:Reid Spencer
Minor tweaks in public headers and a few .cpp files so that LLVM can build successfully with -pedantic and projects using LLVM with -pedantic don't get warnings from LLVM. There's still more -pedantic warnings to fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28453 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-23Print struct return functions and calls as actually returning the hiddenChris Lattner
argument struct pointer, enabling ABI compatibility for the CBE with platforms with strange struct-return ABIs. This fixes 252.eon and CoyoteBench/fftbench on Darwin/X86 among other things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28442 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-23Implement an annoying part of the Darwin/X86 abi: the callee of a structChris Lattner
return argument pops the hidden struct pointer if present, not the caller. For example, in this testcase: struct X { int D, E, F, G; }; struct X bar() { struct X a; a.D = 0; a.E = 1; a.F = 2; a.G = 3; return a; } void foo(struct X *P) { *P = bar(); } We used to emit: _foo: subl $28, %esp movl 32(%esp), %eax movl %eax, (%esp) call _bar addl $28, %esp ret _bar: movl 4(%esp), %eax movl $0, (%eax) movl $1, 4(%eax) movl $2, 8(%eax) movl $3, 12(%eax) ret This is correct on Linux/X86 but not Darwin/X86. With this patch, we now emit: _foo: subl $28, %esp movl 32(%esp), %eax movl %eax, (%esp) call _bar *** addl $24, %esp ret _bar: movl 4(%esp), %eax movl $0, (%eax) movl $1, 4(%eax) movl $2, 8(%eax) movl $3, 12(%eax) *** ret $4 For the record, GCC emits (which is functionally equivalent to our new code): _bar: movl 4(%esp), %eax movl $3, 12(%eax) movl $2, 8(%eax) movl $1, 4(%eax) movl $0, (%eax) ret $4 _foo: pushl %esi subl $40, %esp movl 48(%esp), %esi leal 16(%esp), %eax movl %eax, (%esp) call _bar subl $4, %esp movl 16(%esp), %eax movl %eax, (%esi) movl 20(%esp), %eax movl %eax, 4(%esi) movl 24(%esp), %eax movl %eax, 8(%esi) movl 28(%esp), %eax movl %eax, 12(%esi) addl $40, %esp popl %esi ret This fixes SingleSource/Benchmarks/CoyoteBench/fftbench with LLC and the JIT, and fixes the X86-backend portion of PR729. The CBE still needs to be updated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28438 91177308-0d34-0410-b5e6-96231b3b80d8
