debug: Allow means for targets to opt out of CTF/BTF support
CTF/BTF debug formats can be safely enabled for all ELF-based targets by
default in GCC.
CTF/BTF debug formats now adopt a similar approach as taken for DWARF debug
format via the DWARF2_DEBUGGING_INFO.
- By default, CTF/BTF formats can be enabled for all ELF-based targets.
- By default, CTF/BTF formats can be disabled for all non ELF-based targets.
- If the user passed a -gctf but CTF is not enabled for the target, GCC
issues an error to the user (as is done currently with other debug formats) -
"target system does not support the 'ctf' debug format". Analogous behavior
for -gbtf command line option.
A previous commit disabled the CTF and BTF testcases on the AIX platform. This
is not necessary now that CTF and BTF debug formats are disabled by default on
all non-ELF targets. GCC emits an error message when -gctf/-gbtf is used on
such platforms and these tests will be skipped.
gcc/
* config/elfos.h (CTF_DEBUGGING_INFO): New definition.
(BTF_DEBUGGING_INFO): Likewise.
* doc/tm.texi.in: Document the new macros.
* doc/tm.texi: Regenerated.
* toplev.c: Guard initialization of debug hooks.
gcc/testsuite/
* gcc.dg/debug/btf/btf.exp: Do not run BTF testsuite if target does not
support BTF format. Remove redundant check for AIX.
* gcc.dg/debug/ctf/ctf.exp: Do not run CTF testsuite if target does not
support CTF format. Remove redundant check for AIX.
* lib/gcc-dg.exp: Remove redundant check for AIX.
