Since THUMB_FUNC_START does not insert the ".text" directive, it aligns
more closely with the new FUNC_ENTRY maro and is renamed accordingly.
THUMB_FUNC_START usage has been universally synonymous with the
".force_thumb" directive, so this is now folded into the definition.
Usage of ".force_thumb" and ".thumb_func" is now tightly coupled
throughout the "arm" subdirectory.
gcc/libgcc/ChangeLog:
2021-01-14 Daniel Engel <g...@danielengel.com>
* config/arm/lib1funcs.S: (THUMB_FUNC_START): Renamed to ...
(THUMB_FUNC_ENTRY): for consistency; also added ".force_thumb".
(_call_via_r0): Removed redundant preceding ".force_thumb".
(__gnu_thumb1_case_sqi, __gnu_thumb1_case_uqi, __gnu_thumb1_case_shi,
__gnu_thumb1_case_si): Removed redundant ".force_thumb" and ".syntax".
