Subject: [PATCH v2] xtensa: initialize call_abi in xtensa_tdep
Date: Thu, 20 Aug 2015 12:53:00 -0000	[thread overview]
Message-ID: <1440075160-13310-1-git-send-email-jcmvbkbc@gmail.com> (raw)

Use XSHAL_ABI value provided by xtensa-config.h to correctly initialize
xtensa_tdep.call_abi
This fixes calls to functions from GDB that otherwise fail with the
following assertion in call0 configuration:

  gdb/regcache.c:602: internal-error: regcache_raw_read: Assertion
  `regnum >= 0 && regnum < regcache->descr->nr_raw_registers' failed.

gdb/
	* xtensa-tdep.h (XTENSA_GDBARCH_TDEP_INSTANTIATE): Initialize
	call_abi using XSHAL_ABI macro.
---
Changes v1 -> v2:
- fix call_abi code formatting.
