[llvm-commits] [llvm-gcc] Cumulative Patch 2007-01-07 (Take 2)

[Reid Spencer]

I wish I could retract email.

The patch I just sent didn't have differences for sub-directories in it.
Please don't apply it. Instead use this one which should bring you up to
date with Apple's changes. Again, this applies to r240 of the llvm-gcc
SVN mirror.

Some things to note. If your target is not x86, x86-64, or ppc and your
operating system is not darwin or linux, this probably won't work.
You'll get a link error like this:

../../src-1/gcc/llvm-convert.cpp:3118: undefined reference to `TreeToLLVM::TargetIntrinsicLower(unsigned int, llvm::Value*, llvm::Value*&, llvm::Type const*, std::vector<llvm::Value*, std::allocator<llvm::Value*> >&, llvm::SmallVector<tree_node*, 8u>&, llvm::BasicBlock*, bool, bool)'

That's because the makefiles aren't quite ready to compile a target
specific C++ file yet. Fortunately there is a work around:

1. Edit gcc/config.gcc
2. Find the case statement at line 558
3. Find the pattern that matches your target in the cases that follow. 
4. Add the following right after the "tmake_file" line for your target.
# APPLE LOCAL begin LLVM
        out_cxx_file=i386/llvm-i386.cpp
# APPLE LOCAL end LLVM

For example, find the line that matches this pattern: ^i.*linux
around line 964. That has an example of the correct patch. It looks like
this:

i[34567]86-*-linux* | i[34567]86-*-kfreebsd*-gnu | i[34567]86-*-knetbsd*-gnu)
                        # Intel 80386's running GNU/*
                        # with ELF format using glibc 2
        tm_file="${tm_file} i386/unix.h i386/att.h dbxelf.h elfos.h svr4.h linux.h i386/linux.h"
# APPLE LOCAL begin LLVM
        out_cxx_file=i386/llvm-i386.cpp
# APPLE LOCAL end LLVM
        case ${target} in

The APPLE section is what you add.

Reid.
