Hi,
This patch series change target_ops method to_xfer_partial to return
target_xfer_status and the transfered length, which was discussed
before https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html
Patch #1, #2 and #3 are cleanup and refactor patches, and patch #5
does the change. Patch #4 is to let all to_xfer_partial
implementation not worry about 'len == 0'. With this patch series,
target implementations to to_xfer_partial can set unavailable by
its own, and make it easier to handle unavailable data.
This patch series don't include changes to target ctf and tfile.
I'll do that in next step.
Regression tested on x86_64-linux. Rebuild GDB in the following
ways:
- on x86-linux, with all targets enabled,
- cross build native mingw32,mips-linux,hurd,sparc-linux, gdb on
linux,
- build native powerpc-linux gdb on gcc110
- build spu-elf target on gcc110
- build aix native gdb on gcc111
Is it OK?
*** BLURB HERE ***
Yao Qi (6):
Tweak in memory_error
core_xfer_shared_libraries and core_xfer_shared_libraries_aix returns
ULONGEST
Replace -1 with TARGET_XFER_E_IO
Return early in target_xfer_partial when LEN is zero.
Return target_xfer_status in to_xfer_partial
Update comments to to_xfer_partial implementations.
