[[RESEND & PING]PATCH V3 0/1] Add C-SKY support

2019-06-03 Thread Mao Han 
CC: Mark Wielaard 

This patch add backend support for C-SKY architecture.

FAIL cases on csky:
1. run-backtrace-*
discussed in this thread before, seems can't support with current
core_set_initial_registers.
https://sourceware.org/ml/elfutils-devel/2019-q2/msg00021.html
test binary:
https://github.com/c-sky/test-result/blob/master/elfutils/divzero
https://github.com/c-sky/test-result/blob/master/elfutils/core

2. run-native-test.sh
ssh script problem, can pass if it is ran directly.

3. run-dwarf-getmacros.sh
ssh script problem, the empty string argument is lose,
can pass if it is ran directly.

4. run-deleted.sh
ssh script problem, can pass if it is ran directly.

5. run-reverse-sections-self.sh
elfcopy --reverse-offs dose not work properly on C-SKY object file,
seems not related to arch specific code.

[COMMITTED] tests: elfcopy --reverse-offs should only swap sections next to each other.

2019-06-03 Thread Mark Wielaard 
The run-reverse-sections-self.sh (which really should have been called
"swap-sections") could fail if the ELF file had sections that were not
directly next to each other swapped. Add a check to make sure the swapped
sections are actually directly next to each other.
