Bug ID: 100324
Summary: gcc-10.2.0 (and earlier) fails to build on x86_64, but
has builds just fine aarch64
Product: gcc
Version: 10.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: torel at simula dot no
Target Milestone: ---
I build gcc on multiple architectures natively. Not crosscompiled such as
described in 95317.
Problem: Build of D-lang fails on x86_64, and has for some time. At the same
time it builds and works fine on aarch64 (Cavium Tx2 CN9980, Kunpeng920-6426).
Same version. Not sure when it started, maybe on gcc-9.
Reproducing:
mkdir Build-x86_64
cd Build-x86_64

Removing D from configure line is of course WorkARound (WAR).
Observation: Building on aarch64 with make -j 256 works like a charm, while on
x86_64 it sometimes stops and I have to continue serially, i.e. only with make.
Any suggestions?
