PATCH for RSB/gdb
I have attached a patch for RSB/gdb-7.11 that brings the sis simulator
up to date and adds support for leon2/3 emulation. Some seg-faults have
also been fixed, and breakpoints and watchpoints work correctly with gdb
and DDD now. The patch is pulled in from gaisler.org, and consists of
the following 9 parts:
0001-sim-erc32-Use-gdb-callback-for-UART-I-O-when-linked-.patch
0002-sim-erc32-Access-memory-subsystem-through-struct-mem.patch
0003-sim-erc32-Move-local-extern-declarations-into-sis.h.patch
0004-Add-support-for-LEON3-processor-emulation.patch
0005-sim-erc32-Add-support-for-LEON2-processor-emulation.patch
0006-sim-erc32-Updated-documentation.patch
0007-sim-erc32-Add-data-watchpoint-support.patch
0008-Add-watchpoint-support-to-gdb-simulator-interface.patch
0009-sim-erc32-Added-back-original-run.c.patch
The 'run' command now also supports leon2/3 emulation, by adding '-a
-leon2' or '-a leon3' at startup. This can be used to automate testing
of the erc32, leon2 and leon3 bsp's. I would suggest that the 'sis' bsp
is dropped for 4.12 as it is no longer needed ...
Jiri.

Re: PATCH for RSB/gdb
The previous patch also contained a non-related fix to binutils, sorry
for that. I have attached the correct patch.

[PATCH 0/7] Update Tools on Master Plus SPARC Fixes
Hi This is my patch series updated to include some SPARC updates and fixes from Jiri. This includes a binutils fix for #2802 (dl05) which will need to be backported to 4.11.1. I will push soon unless someone complains mightily. :) For the 4.12 releases, we will need a gcc 7 release. For mipstx39, we need gdb 7.12.1 or 7.13. Not worth figuring out which patches make 7.11 and 7.12 build. --joel Jiri Gaisler (2): binutils-2.26-1: Add patch for unaligned reloc on SPARC binutils-2.27-1: Add patch for unaligned reloc on SPARC Joel Sherrill (5): rtems-default.bset: Update to binutils 2.27 rtems-default.bset: Update to gcc-6-20161110 and newlib 2.4.0.20161025 rtems-default.bset: Update to gdb 7.12 rtems-gdb-7.11-1.cfg: Add support for leon2/leon3 to sis rtems-gdb-7.12-1.cfg: Add support for leon2/leon3 to sis rtems/config/4.12/rtems-default.bset | 6 ++-- rtems/config/tools/rtems-binutils-2.26-1.cfg | 5 rtems/config/tools/rtems-binutils-2.27-1.cfg | 34 ++ ...tems-gcc-6-20161110-newlib-2.4.0.20161025-1.cfg | 23 +++ rtems/config/tools/rtems-gdb-7.11-1.cfg| 8 ++--- rtems/config/tools/rtems-gdb-7.12-1.cfg| 29 ++ rtems/config/tools/rtems-mipstx39-gdb-7.9-1.cfg| 2 +- 7 files changed, 97 insertions(+), 10 deletions(-) create mode 100644 rtems/config/tools/rtems-binutils-2.27-1.cfg create mode 100644 rtems/config/tools/rtems-gcc-6-20161110-newlib-2.4.0.20161025-1.cfg create mode 100644 rtems/config/tools/rtems-gdb-7.12-1.cfg -- 1.8.3.1 ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

[PATCH 3/7] rtems-default.bset: Update to gdb 7.12
Clean up comments in mipstx39 file. It doesn't build in gdb 7.12.
It is fixed on the gdb master and 7.12 branch. When 7.12.1 comes
out, we will need to bump to that.

Re: PATCH for RSB/gdb
I just posted a patch series which should include all of my updates and Jiri's patches. Please review.

RFC - Remove sis before 4.12 Branches
Hi The sis variant of the sparc/erc32 BSP has existed a LONG time in RTEMS. It was needed to turn on about 50 lines of assembly that were needed to initialize the simulator but not the real erc32. This reflects the simulator existing before the hardware. The real erc32 configuration disables that code because it is not needed and thus undesirable for flight configurations. Jiri Gaisler fixed the simulator well over a year ago so that the simulator is initialized in the same state as the real HW. This lets the erc32 BSP variant (without the special code) work on gdb/sis. Thus this variant isn't needed any longer. If this were ANY other BSP, this would barely rate a ticket. But this BSP variant was added in January 2006 and is featured in the Hello World task and various other instructions. There is no technical reason to keep this BSP but it is going to be a bit more difficult to completely clean up. Any objections to removing the unnecessary sparc/sis BSP variant before 4.12 branches? I plan to file a ticket and prepare a patch. It will take a village to make sure we catch all the places this is in instructions though. Thanks. --joel ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
