I compiled the RTEMS testsuite with this compiler and run it on an NGMP board. The results are all right. -- Sebastian Huber, embedded brains GmbH Address : Dornierstr. 4, D-82178 Puchheim, Germany Phone : +49 89 189 47 41-16 Fax : +49 89 189 47 41-09 E-Mail : sebastian.hu...@embedded-brains.de PGP : Public key available on request.

Fine with me. Does spatc-elf need a refresh on its multilibs? --joel
Re: [PATCH] RTEMS: select SPARC multilibs
Hi, Thanks for review and testing! Then I will apply it. Thanks for bringing up the sparc-elf. I think we would want the LEON3 in the t-elf, however I have to verify the LEON newlib C state and mflat etc. before activating that.

[PATCH] RTEMS: select SPARC multilibs
Recent support for mcpu=leon3v7 and muser-mode were added
to GCC. Update the RTEMS multilib for sparc to the
following combinations:
v7- ./
leon3 muser-mode - leon3/user-mode/
leon3v7 muser-mode- leon3v7/user-mode/
v8- v8/
v7 soft-float - soft/
leon3 soft-float muser-mode - soft/leon3/user-mode/
leon3v7 soft-float muser-mode - soft/leon3v7/user-mode/
v8 soft-float - soft/v8/
I think this would be good for 4.8, 4.9 and trunk.
