Author: rth Date: Sat Aug 21 19:05:40 2010 New Revision: 163446 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=163446 Log: Vectorize fast path of _cpp_clean_line. * configure.ac (AC_C_BIGENDIAN, AC_TYPE_UINTPTR_T): New tests. (ssize_t): Check via AC_TYPE_SSIZE_T instead of AC_CHECK_TYPE. (ptrdiff_t): Check via AC_CHECK_TYPE. * config.in, configure: Rebuild. * system.h: Include stdint.h, if available. * lex.c (WORDS_BIGENDIAN): Provide default. (acc_char_mask_misalign, acc_char_replicate, acc_char_cmp, acc_char_index, search_line_acc_char, repl_chars, search_line_mmx, search_line_sse2, search_line_sse42, init_vectorized_lexer, search_line_fast): New. (_cpp_clean_line): Use search_line_fast. Restructure the fast loop to make it clear when we're leaving the loop. Stay in the fast loop for non-trigraph '?'. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45538
