Subject: [PATCH] xtensa: initialize call_abi in xtensa_tdep
|
|
|
|
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.
