Subject: [PATCH] aix.h (ASM_DECLARE_FUNCTION_NAME): Call named_section() or
text_section() as appropriate instead of emitting text...
* aix.h (ASM_DECLARE_FUNCTION_NAME): Call named_section() or
text_section() as appropriate instead of emitting text csect
pseudo-op directly.
(TEXT_SECTION_ASM_OP): Only require default 32-bit alignment.
(UNIQUE_SECTION): Define macro.
(ASM_OUTPUT_SECTION_NAME): Define macro.
* rs6000.c (rs6000_override_options): Disable -ffunction-sections
on AIX if debugging and -fdata-sections always.
