https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85478 --- Comment #8 from Andreas Krebbel --- The problem is similar to PR83753 but with a different call-chain. Richard Sandiford fixed it by adding: /* First cope with the degenerate case of a single-element vector. */

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85478 --- Comment #7 from Andreas Krebbel --- The cross from comment #6 did not trigger the problem because I accidentally built it with --disable-checking. Dropping this and adding --with-long-double-128 triggers the ICE on a full cross as well as on

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85478 --- Comment #6 from Andreas Krebbel --- The difference I have seen so far was triggered by building the cross with "--without-headers". As a result the detected glibc version is 0.0: config.log: configure:28145: checking for target glibc

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85478 --- Comment #4 from Andreas Krebbel --- Indeed it does not appear to fail with a cross from x86. I've checked with r259518 on s390x as well as on x86. With an x86 cross no tree dump is generated after 012t.ompexp and the generated assembler file

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85478 --- Comment #3 from Richard Biener --- Hmm, it doesn't seem to ICE for me (with a cross from x86_64-linux). I configured with --target s390x-linux-gnu
