bl-0.0.1 (base : gcc-4.2.1) build binary for linux

part 2 (for sourceforge's 100 MB limit)

This version sample gcc frontend can compile in gcc-core-4.3.0 or maybe latter (but very unstable !!)

test environment : gcc-4.3.0 only

Install example :

$ tar jxvf gcc-core-4.3.0.tar.bz2
$ tar jxvf bl-0.0.1-for-gcc-4.3.0.tar.bz2
$ mv bl gcc-4.3.0/gcc/
$ mkdir bl-build
$ mv bl-build
$ ../gcc-4.3.0/configure --prefix=/usr/local/build-gcc --enable-languages=bl --enable-checking=tree
$ make && make install

To support gcc 4.3.0, mostly code were contributed by SATO daisuke (QLeap).

for init builtin types and functions :

(mostly code from the c crontend)

bl.h, bl-builtins.c, and modified Make-lang.in

a part of sample gcc frontend build environment for QEMU.
(FreeBSD 7.0 minimal install version)

This is a minimal frontend sample.

For any input .bl file, this frontend only output an executable file or assembly source code correcponding to the following c source code :

int main() {return 0;}



For example :

$ cat null.bl
$ ../bin/gcc null.bl
$ ls
a.out null.bl
$ ./a.out
$ ../bin/gcc -S null.bl
$ cat null.s
.file "null.bl"
.text
.globl main
.type main, @function
main:
pushl %ebp
movl %esp, %ebp
movl $0, %eax
popl %ebp
ret
.size main, .-main
.ident "GCC: (GNU) 4.3.0"
.section .note.GNU-stack,"",@progbits

Build example

$ mkdir -p /usr/local/build-gcc/build-bl
$ tar jxvf gcc-4.3.0.tar.bz2 -C /usr/local/build-gcc
$ tar jxvf bl-minimal-4.3.0.tar.bz2 -C /usr/local/build-gcc/gcc/
$ cd /usr/local/build-gcc/build-bl
$ ../gcc-4.3.0/configure --prefix=/usr/local/build-gcc/build-bl --enable-languages=bl --enable-checking=all --disable-nls --disable-bootstrap
$ make && make install
