gdb: fix simulator build failures

2016-08-04T22:16:22+00:00

Following reports from me of build failures of the GDB simulator for the Blackfin architecture, Waldemar cooked a patch (0005-fix-sim-compile.patch) that removes the typedef of SIM_CPU, because there was a redefinition of this typedef for Blackfin. This was not causing an issue with recent compilers as redefining the same typedef is valid with recent compilers, but was causing build failures with gcc 4.4.x. However, by removing the common definition of SIM_CPU, this patch broke the build of the GDB simulator on other architectures, which did not had an architecture-specific redefinition of SIM_CPU (unlike Blackfin). The crux of the problem is in a commit from Mike Frysinger, that tries to refactor the SIM_CPU definition into a common one. Except that it leaves a redefinition of it for Blackfin. Removing this second definition however doesn't easily work, due to include ordering issues. The easiest solution is to simply revert the patch from Mike Frysinger. This allows to fix the build for all architectures and all compiler versions.

With this config you can bootup a Linux kernel in GDB simulator and test Blackfin kernel and userland. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni

package/gdb: fix gnulib issue with musl and uClibc toolchains

2016-07-24T19:52:29+00:00

Starting with gdb 7.11, the bundled gnulib want to use rpl_gettimeofday (gettimeofday replacement) due bad guessing when cross-compiling with musl and uClibc toolchains. Instead of patching gnulib configure script to fix the test, use gl_cv_func_gettimeofday_clobber=no to not use rpl_gettimeofday. Thanks to Thomas Petazzoni to suggest this patch.

package/gdb: add dependency on host-textinfo

2016-07-06T18:15:14+00:00

Starting with gdb 7.10, gdb wants to re-generate its documentation. We were trying to avoid that by patching the Makefiles, but it wasn't working in all situations. So, we simply add a dependency on host-texinfo in all case.

gdb: add dependency on host-flex and host-bison for Git versions

gdb: add dependency on host-texinfo

2016-07-05T13:04:26+00:00

Just like binutils, when gdb is fetched from git, it wants to re-generate its documentation. We were trying to avoid that by patching the Makefiles, but it wasn't working in all situations. So, we simply add a dependency on host-texinfo when gdb is fetched from git, and remove our hackhish work-around.

gdb: enable simulator support for host build

2016-05-31T21:14:00+00:00

Add an option to enable GDB simulator support, so it can be used to test some no-MMU systems. Newer GDB Blackfin Simulator need a workaround for in-tree compile. It doesn't break for older Buildroot supported GDB Blackfin Simulator. Signed-off-by: Waldemar Brodkorb Signed-off-by: Thomas Petazzoni
