Subject: [PATCH 1/8] configure gdb build system for supporting btrace on arm processors
Date: Fri, 26 Feb 2021 03:45:55 +0100 [thread overview]
Message-ID: <20210226024602.55057-2-zied.guermazi@trande.de> (raw)
In-Reply-To: <20210226024602.55057-1-zied.guermazi@trande.de>
This patch adds the possibility to build GDB with support for branch tracing
using ARM CoreSight traces
new flag is --with-arm-cs
gdb/ChangeLog
* Makefile.in LIBOPENCSD_C_API: set the flag.
* config.in LIBOPENCSD_C_API: undefine it if
libopenocsd library is available.
* configure: Regenerated.
* configure.nat: add nat/linux-btrace.o to the build
for aarch64 and arm
* top.c (print_gdb_configuration): add --with-arm-cs
or --without-arm-cs according to the configuration.
gdbserver/ChangeLog
* gdbserver/configure: Regenerated.
gdbsupport/ChangeLog
* gdbsupport/common.m4: check --with-arm-cs configuration
flag, perf_event and opencsd_c_api to set compilation flags.
* gdbsupport/configure: Regenerated
