From: Trevor Saunders <tbsaunde+...@tbsaunde.org>
Hi,
basically just $subject, always define HAVE_AS_LEB128, and then use if / else
instead of #ifdef. Note the diff has a bit of whitespace noise, so there's a
-w diff below the full one.
bootstrapped and regtested on x86_64-linux-gnu, ok?
Trev
gcc/ChangeLog:
2016-08-20 Trevor Saunders <tbsaunde+...@tbsaunde.org>
* acinclude.m4 (gcc_GAS_CHECK_FEATURE): Support doing an action
if the feature isn't available.
* configure: Regenerate.
* configure.ac: define HAVE_AS_LEB128 to 0 when not available.
* dwarf2asm.c (dw2_asm_output_data_uleb128): Always compile code
for HAVE_AS_LEB128.
(dw2_asm_output_data_sleb128): Likewise.
(dw2_asm_output_delta_uleb128): Likewise.
(dw2_asm_output_delta_sleb128): Likewise.
* except.c (output_one_function_exception_table): Likewise.
(dw2_size_of_call_site_table): Likewise.
(sjlj_size_of_call_site_table): Likewise.
