    • ia64: Update vector multiply pattern names; delete dot_prod · 1312c276 
      With the even/odd v4hi multiply pattern names, we'll automatically
generate the same code for dot_prodv4hi.  The dot_prodv8qi pattern
was actively incorrect wrt output mode.

        * config/ia64/vect.md (smulv4hi3_highpart): New.
        (umulv4hi3_highpart): New.
        (vec_widen_smult_even_v4hi): Rename from pmpy2_even.
        (vec_widen_smult_odd_v4hi): Rename from pmpy2_odd.
        (udot_prodv8qi, sdot_prodv8qi): Remove.
        (sdot_prodv4hi, udot_prodv4hi): Remove.
        * config/ia64/ia64.c (ia64_expand_dot_prod_v8qi): Remove.
        * config/ia64/ia64-protos.h: Update.

    • Fix --produce_manifest flag in validate_failures.py. · 29476fe1 
      When I added the functionality to use other summary files for
reporting, I broke the generation of manifests. When sum files are
passed on, we need to use the list. Otherwise, we need to find summary
files in the build directory.

This patch factors out that logic into a new function and calls it
from both the reporting and generation routines.

Committed to trunk.

	Rename from GetSumFiles.
	(GetSumFiles): Factor out of CheckExpectedResults.
