4 | Subject: [PATCH 01/16] [Patch, microblaze]: Add wdc.ext.clear and | ||
5 | wdc.ext.flush insns | ||
6 | |||
7 | Added two new instructions, wdc.ext.clear and wdc.ext.flush, | ||
8 | to enable MicroBlaze to flush an external cache, which is | ||
9 | used with the new coherency support for multiprocessing. | ||

6 | Added backtrace support without debugging information. | ||

8 | Earlier backtrace used to work only when debug information is available. | ||
9 | Previous pc & sp values are calculated incorrectly due to which backtrace | ||
10 | was failing. | ||
11 | |||
12 | In this patch, previous frame sp & pc values are calculated correctly | ||
13 | in microblaze_frame_cache function and supplied them to | ||

4 | Subject: [PATCH 15/16] [LOCAL]: upstream change to garbage collection sweep | ||
5 | causes mb regression | ||
6 | |||
7 | Upstream change for PR13177 now clears the def_regular during gc_sweep of a | ||
8 | section. (All other archs in binutils/bfd/elf32-*.c received an update | ||
9 | to a warning about unresolvable relocations - this warning is not present | ||
10 | in binutils/bfd/elf32-microblaze.c, but this warning check would not | ||
11 | prevent the error being seen) | ||
12 | |||
13 | The visible issue with this change is when running a c++ application | ||
14 | in Petalinux which links libstdc++.so for exception handling it segfaults | ||
15 | on execution. | ||
16 | |||
17 | This does not occur if static linking libstdc++.a, so its during the | ||
18 | relocations for a shared lib with garbage collection this occurs | ||
19 | |||
20 | Signed-off-by: David Holsgrove <david.holsgrove@xilinx.com> | ||
21 | Upstream-Status: Pending | ||
