flags.h (flag_function_sections): Declare.
* flags.h (flag_function_sections): Declare.
* toplev.c (flag_function_sections): Define.
(compile_file): Add warnings when -ffunction-sections is
used with -g, or profiling. Disable -ffunction-sections
when profiling is used. Add warning when -ffunction-sections
is used on a target that doesn't support it.
* varasm.c (named_section): Make a copy of the section name
in case the original is in temporary storage.
(function_section): Set DECL_SECTION_NAME for each function
if flag_function_sections is on and the target supports it.
* dbxout.c (dbxout_function_end): New function.
(dbxout_function): Call dbxout_function_end if using extensions
and flag_function_sections is on.
* sparc/sysv4.h (ASM_OUTPUT_SECTION_NAME): Prefix a function
section's name with ".text%" when -ffunction-sections.
