Bug ID: 113750
Summary: [14 Regression] ICE in vect building
gcc/m2/gm2-libs/NumberIO.mod
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
Target Milestone: ---
Host: aarch64-linux
Target: aarch64-linux
This is on cfarm185 (aarch64-linux) with a compiler configured:
../src/configure --prefix=... --enable-languages=all
-save-temps is not giving me any intermediate and fdump-tree-gimple gives no
output, will have figure out how to reduce this.
