Subject: [PATCH] xtensa: initialize call_abi in xtensa_tdep
Date: Sat, 06 Jun 2015 22:06:00 -0000 [thread overview]
Message-ID: <1433628336-24058-1-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.
