Tested on x86_64-darwin21 and i686-darwin9, pushed to trunk, thanks, Iain --- 8< --- System tools from Darwin10 onwards have moved the exceptions tables from the __DATA segment to the __TEXT one. They also revised the relocations used for typeinfo. While Darwin9 was not changed at the time, in fact the tools there are equally happy with the revised scheme - and therefore at present there seems no reason to special-case it. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> gcc/ChangeLog: * config/darwin-sections.def (darwin_exception_section): Move to the __TEXT segment. * config/darwin.cc (darwin_emit_except_table_label): Align before the exception table label. * config/darwin.h (ASM_PREFERRED_EH_DATA_FORMAT): Use indirect PC- relative 4byte relocs. --- gcc/config/darwin-sections.def | 2 +- gcc/config/darwin.cc | 1 + gcc/config/darwin.h | 2 +- 3 files changed, 3 insertions(+), 2 deletions(-)
