Author: andrew Date: Sun Dec 14 16:28:53 2014 New Revision: 275767 URL: https://svnweb.freebsd.org/changeset/base/275767 Log: Clean up our ARM assembly: MFC 275256: Switch to the ARM unified assembly language as the clang integrated as only supports it. Binutils supports it when the ".syntax unified" directive is set. Sponsored by: ABT Systems Ltd MFC 275264: Update _ENTRY to use _EENTRY to reduce the common code. MFC 275321: Remove extra labels, ENTRY_NP already provides them. Sponsored by: ABT Systems Ltd MFC 275322: Correctly a few incorrect uses of ENTRY/EENTRY and END/EEND Sponsored by: ABT Systems Ltd MFC 275416: Fix the name of the coprocessor to include the "p" prefix, the clang integrated assembler expects this. Sponsored by: ABT Systems Ltd MFC 275418: Switch to unified syntax so these can be built with clang 3.5. Sponsored by: ABT Systems Ltd MFC 275519: Add missing END macros to some of the xscale functions. Sponsored by: ABT Systems Ltd MFC 275520: Use the unified syntax in a few more assembly files Sponsored by: ABT Systems Ltd MFC 275521: Set the alignment to 4-bytes after a string as clang 3.5 can switch to thumb mode if this is incorrect. Sponsored by: ABT Systems Ltd MFC 275522: Place the literal pool after a RET otherwise clang 3.5 tries to put it too far away from a ldr psuedo instruction. With this clang will place the literal value here where it's close enough to be loaded. Sponsored by: ABT Systems Ltd MFC 275523: Switch to an armv6k cpu, without this clang 3.5 complains "bx lr" is unsupported as it needs a newer cpu. Sponsored by: ABT Systems Ltd MFC 275524: Switch to a .cpu directive. These will work when clang 3.5 is imported where the .arch directive is a nop.
