[Bug driver/111527] COLLECT_GCC_OPTIONS option hits single-variable limits too early
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111527 --- Comment #14 from Randy MacLeod --- There is a revised patch that has finally been tested after someone's vacation. Deepthi, please share the link to the patch on this list once it's sent.
[Bug tree-optimization/115824] [12 Regression] Strange -Warray-bounds warning when assigning an initializer list to a vector of pointers
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115824 --- Comment #5 from Randy MacLeod --- Andrew, Is Rogério's confirmation, that reverting r12-10250-g8ec265c1464dec avoids the error, sufficient to revert the commit on 12.4 or do you want someone to write a test case, confirm it works on 12.3's tag and then do a git bisect b/w 12.3 and 12.4 ? It would be nice to have the 1-element copy optimization, if we can figure out what's causing the indexing error. I may spend more time and look at the preprocessor output when I'm back from a week off work.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81317 --- Comment #28 from Randy MacLeod --- Alex, thanks for confirming, I was worried that it was one of the _perfectly_ sensible local patches we have in YP. ;-) FYI, a local toolchain expert has started working on this defect so stay tuned / keeep refreshing.

--- Comment #18 from Randy MacLeod ---
With both patches applied:
1. The "minimal testcase produced by the delta utility" no longer ICEs the
toolchain.
2. The "smaller reproducer with manual work-around " DOES STILL result in an
ICE as does the libjpeg-turbo build as you'd expect.
Here's the patch I'm using just to keep myself honest:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81317 --- Comment #1 from Randy MacLeod --- I also used the delta utility to produce a larger reproducer. I'll attach it as jdcolor-altivec-testcase-min.i along with the full preprocessor output in case it's useful to have additional context.
[Bug c/81317] New: builtin_vec_ld fails for powerpc with altivec
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81317 Bug ID: 81317 Summary: builtin_vec_ld fails for powerpc with altivec Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: randy.macleod at windriver dot com Target Milestone: --- When building libjpeg-turbo using oe-core's build system with: master with HEAD at: 325f087 image.bbclass: create root symlinks in nativesdk target sysroot on an Ubuntu-16.04.1 LTS host, I encountered a toolchain ICE. I used creduce to produce a minimal test case: $ cat testcase.i jsimd_ycc_extbgrx_convert_altivec_outptr; __attribute__ ( ( altivec ( __builtin_vec_ld ( 1, jsimd_ycc_extbgrx_convert_altivec_outptr ) -- The compile line and error are: $ powerpc-oe-linux-gcc -m32 -mhard-float -mcpu=7400 -mno-spe -Wall -Wextra --sysroot=/buildarea/rmacleod/src/distro/yocto/b/sd-ppc/tmp-glibc/work/ppc7400-oe-linux/libjpeg-turbo/1_1.5.2-r0/recipe-sysroot -DHAVE_CONFIG_H -I. -I../../libjpeg-turbo-1.5.2/simd -I.. -I../../libjpeg-turbo-1.5.2 -Wall -maltivec -O2 -pipe -g -feliminate-unused-debug-types -fdebug-prefix-map=/buildarea/rmacleod/src/distro/yocto/b/sd-ppc/tmp-glibc/work/ppc7400-oe-linux/libjpeg-turbo/1_1.5.2-r0=/usr/src/debug/libjpeg-turbo/1_1.5.2-r0 -fdebug-prefix-map=/buildarea/rmacleod/src/distro/yocto/b/sd-ppc/tmp-glibc/work/ppc7400-oe-linux/libjpeg-turbo/1_1.5.2-r0/recipe-sysroot-native= -fdebug-prefix-map=/buildarea/rmacleod/src/distro/yocto/b/sd-ppc/tmp-glibc/work/ppc7400-oe-linux/libjpeg-turbo/1_1.5.2-r0/recipe-sysroot= -c testcase.i -fPIC -DPIC -o .libs/libsimd_altivec_la-jdcolor-altivec.o testcase.i:1:1: warning: data definition has no type or storage class jsimd_ycc_extbgrx_convert_altivec_outptr; ^~~~ testcase.i:1:1: warning: type defaults to 'int' in declaration of 'jsimd_ycc_extbgrx_convert_altivec_outptr' [-Wimplicit-int] testcase.i:4:21: internal compiler error: Segmentation fault ( 1, jsimd_ycc_extbgrx_convert_altivec_outptr ) ^ Please submit a full bug report, with preprocessed source if appropriate. See <https://gcc.gnu.org/bugs/> for instructions. I have also confirmed that using 7.1.1-beta aka 7-20170629 does not fix the ICE. I can't easily test the gcc master branch so I await your suggestion. oe-core builds it's own toolchain but we're close to this version: $ powerpc-oe-linux-gcc -v Using built-in specs.
