GCC modified for the FreeChainXenon project

This message is a long write-up for a patch that simply adds a common routine for printing the "vector_foo_pattern: detected:" messages. The reason for doing this is that some routines check for target support themselves and some leave it to vect_pattern_recog_1. Those that leave it to vect_pattern_recog_1 currently print these "detected:" messages if the statements have the right form, even if the pattern is eventually discarded. IMO that's useful, and a lot of existing scan tests rely on it. However, a later patch makes patterns do their own testing, and stops them creating pattern statements until the tests have passed. This means (a) they need to print the "detected:" message earlier and (b) the pattern statement won't be around to print. The patch therefore makes all routines print the original statement rather than the pattern one. That information isn't obvious otherwise, whereas vect_pattern_recog_1 already prints the pattern statement in the case of a successful match. This also avoids the previous situation in which a routine could print "detected:" and then silently bail out before saying what had been detected. 2018-06-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-patterns.c (vect_pattern_detected): New function. (vect_recog_dot_prod_patternm, vect_recog_sad_pattern) (vect_recog_widen_mult_pattern, vect_recog_widen_sum_pattern) (vect_recog_over_widening_pattern, vect_recog_widen_shift_pattern (vect_recog_rotate_pattern, vect_recog_vector_vector_shift_pattern) (vect_recog_mult_pattern, vect_recog_divmod_pattern) (vect_recog_mixed_size_cond_pattern, vect_recog_bool_pattern) (vect_recog_mask_conversion_pattern) (vect_try_gather_scatter_pattern): Likewise.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
