I've been having fantastic success building gcc. I have got it
to iterate through the entire build (as far as I can tell) now.
Then finally I ran into an internal compiler error which I haven't seen
before. One of the gcc options must have triggered something off.
Perhaps it was -Wwrite-strings, or maybe the -O2 (I normally use
-Os for a completely unrelated reason). Either way, I need to find
out how to switch off those flags. I'll also try to fix the compiler
internal error in i370.md.
This problem was due to the build being done with 64-bit
long long enabled - something i370.md can't cope with.
I forced it off with these two things:
configure:
main ()
{
! long long int i;
;
return 0;
}
--- 3196,3202 ----
int
main ()
{
! zlong long int i;
hwint.h:
#if !defined HAVE_LONG_LONG
! # if GCC_VERSION >= 3000 && !PUREISO && defined(WANT64)
# define HAVE_LONG_LONG 1
# define SIZEOF_LONG_LONG 8
Now at the end of the build, I can save the output, and do a
grep "^i370-mvspdp-gcc" to get all the source files that need to be
compiled. I could attempt to use the .o files (that are really .s)
directly, but that's not something I really need.
The auto-host.h looks fine, plus I have the generated files.
I still need to clean up the scripts further (the below is a work in
progress), and I need to write the programs that will generate the
compile JCL and then try it out!
Part of the cleanup will hopefully get around the multiple make failures ...
+ make
+ cp gcc/config/i370/dummy_config.h gcc/config.h
+ make
+ cp gcc/config/i370/i370-mvspdp-gcc2 ../mvscross/bin/i370-mvspdp-gcc
+ make
:-)
