This depends on fixing PR bootstrap/44512 and PR bootstrap/44637 (for ppc),
and on the factored-out patches I posted earlier:
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg02492.html
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg02452.html
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg02495.html
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg02618.html
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg02645.html
Bootstrap testing for the patch for PR bootstrap/44637 is delayed because of
issues with rs6000 test platform availability, performance, and either
machine or toolchain (java) configuration.
I have checked all the patches in order into the multi-target-20100625-branch,
and sucessfully bootstrapped and regression tested (against the
branchpoint, trunk
revision 161392/161394) with and without --enable-build-with-cxx
on i686-pc-linux-gnu.
I have also confirmed that an i686-pc-linux-gnu X ppc-elf+spu-elf compiler
can be built using configure options:
--target=ppc-elf --with-extra-target-list=spu-elf
and building the makefile target 'all-gcc', and that the resulting cc1
can compile a simple function for both architectures:
[amylaar@laria gcc]$ cat foo.c
int foo ()
{
return 42;
}
[amylaar@laria gcc]$ ./cc1 -quiet -O2 foo.c
[amylaar@laria gcc]$ cat foo.s
.file "foo.c"
.section ".text"
.align 2
.globl foo
.type foo, @function
foo:
li 3,42
blr
.size foo, .-foo
.ident "GCC: (GNU) 4.6.0 20100625 (experimental)"
[amylaar@laria gcc]$ cat foop.c
int foo () __attribute__ ((target_arch ("spu-elf")));
int foo ()
{
return 42;
}
[amylaar@laria gcc]$ ./cc1 -quiet -O2 foop.c
[amylaar@laria gcc]$ cat foop.s
.file "foop.c"
.arch "spu-elf"
.text
.align 2
.align 3
.global foo
.type foo, @function
foo:
il $3,42
bi $lr
.size foo, .-foo
.ident "GCC: (GNU) 4.6.0 20100625 (experimental)"
