Hello,
we use currently GCC 4.9.2 for the SPARC. Unfortunately two patches are
missing in this version:
2014-11-07 Daniel Hellstrom <dan...@gaisler.com>
Backport from mainline
* config.gcc (sparc-*-rtems*): Clean away unused t-elf.
* config/sparc/t-rtems: Add leon3v7 and muser-mode multilibs.
2014-11-06 Daniel Hellstrom <dan...@gaisler.com>
Backport from mainline
* config.gcc (sparc*-*-*): Accept mcpu=leon3v7 processor.
* doc/invoke.texi (SPARC options): Add mcpu=leon3v7 comment.
* config/sparc/leon.md (leon3_load, leon_store, leon_fp_*): Handle
leon3v7 as leon3.
* config/sparc/sparc-opts.h (enum processor_type): Add LEON3V7.
* config/sparc/sparc.c (sparc_option_override): Add leon3v7
support.
* config/sparc/sparc.h (TARGET_CPU_leon3v7): New define.
* config/sparc/sparc.md (cpu): Add leon3v7.
* config/sparc/sparc.opt (enum processor_type): Add leon3v7.
Both patches are vital.
Daniel, which GCC version do you use for your latest RCC tool chain?
Maybe we should use the same for the current RTEMS SPARC GCC. An
alternative is to just add these two patches on top of GCC 4.9.2.
