This is the second stab at https://gcc.gnu.org/pipermail/gcc-patches/2026-January/704823.html, which concerns cleaning up some testcases in gcc.dg/vect/complex. The original commit message reads: --------------------------------------------------------------------------- Some of the testcases in the gcc.dg/vect/complex directory try to match "stmt.*$internal_fn" in the slp1/vect logs, which leads to many false positives; this patch changes this to "add new stmt: \[^\n\r]*$internal_fn", making sure that the log fragments matched in this way are limited to single lines and correspond to actual newly created GIMPLE statements. This main change results in some fallout, necessitating the following additional tweaks: - For fast-math testcases, replace the "1"s in scan-tree-dump-times directives by appropriate counts. - XFAIL bb-slp and vect testcases featuring integral types, since the cadd{90,270} optabs are not implemented for integral modes. - Disable some FP16 tests for arm targets due to absence of cadd{90,270} for V8HF. - Replace "target { X } && ! target { Y }" selectors with the correct "target { X && { ! Y } }" form. - In bb-slp-complex-add-pattern-long.c, adjust the testcase header to match other tests so that different scan-tree-dump-times directives can be switched off selectively. - In bb-slp-complex-add-pattern-long.c, remove an extraneous scan for "Found COMPLEX_ADD_ROT90". - In bb-slp-complex-add-pattern-int.c, use vect_complex_add_int instead of vect_complex_add_byte. --------------------------------------------------------------------------- Following Tamar's feedback, tweaks 2 and 3 above have been fixed by these changes since v1: - Change what dg-add-options does for arm_v8_3a{,_fp16}_complex_neon so that the correct flags are returned regardless of configure-time values of -mfpu. - For integer tests, require MVE rather than AdvSIMD from the arm backend's side, as only that ISA has cadd{90,270} for integral modes. - Un-XFAIL testcases that gcc is currently able to vectorize, separately for the arm and aarch64 backends. Re-regtested on aarch64 (with and without SVE2) and arm. gcc/testsuite/ChangeLog: * gcc.dg/vect/complex/bb-slp-complex-add-pattern-int.c: Adjust testcase. * gcc.dg/vect/complex/bb-slp-complex-add-pattern-long.c: Likewise. * gcc.dg/vect/complex/bb-slp-complex-add-pattern-short.c: Likewise. * gcc.dg/vect/complex/bb-slp-complex-add-pattern-unsigned-int.c: Likewise. * gcc.dg/vect/complex/bb-slp-complex-add-pattern-unsigned-long.c: Likewise. * gcc.dg/vect/complex/bb-slp-complex-add-pattern-unsigned-short.c: Likewise. * gcc.dg/vect/complex/complex-add-pattern-template.c: Likewise. * gcc.dg/vect/complex/complex-add-template.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-double.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-float.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-pattern-double.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-pattern-float.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-pattern-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-double.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-pattern-double.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-pattern-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-pattern-half-float.c: * gcc.dg/vect/complex/vect-complex-add-pattern-byte.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-int.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-long.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-short.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-unsigned-byte.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-unsigned-int.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-unsigned-long.c: Likewise. * gcc.dg/vect/complex/vect-complex-add-pattern-unsigned-short.c: Likewise. * lib/target-supports.exp: (check_effective_target_arm_v8_3a_complex_neon_ok_nocache): Add explicit "+simd" and tighten check-compile code fragment.

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.
