Bug ID: 85289
Summary: Fails to build libgcc.a multilib for v8-m.base/nofp
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: simon at pushface dot org
Target Milestone: ---
Host: x86_64-apple-darwin15
Target: arm-eabi
Build: x86_64-apple-darwin15
This is with r258387 (20180309); updated to today, r259222, same problem. Was
OK at 20180207.
I’m wondering whether the change at r257904 could be the reason?
I’ve filed this as a target issue, was that right? it does stop the compiler
build.

which means that __STDC_HOSTED__ was defined to 1.
This can’t be the case for all multilibs, because the following were built:
