Bug ID: 94835
Summary: ICE in vague_linkage_p, at cp/decl2.c:2041
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: casner at acm dot org
Target Milestone: ---
I am working on a pdp11-elf32 target in binutils with the goal of being able to
compile C++ for the PDP11 (an effort instigated by Paul Koning, gcc PDP11
maintainer). I have a first implementation running, so now I am trying to
build g++ and libstdc++v3 to go with it.
I am attempting to build the gcc tree with newlib and libgloss symlinked in and
with the binutils components installed at the prefix and with gcc configured as
follows:
../configure --target=pdp11-elf32 --prefix=/usr/local --enable-languages=c,c++
--disable-libssp --disable-libgfortran --disable-libobjc --with-gmp=/opt/local/
--with-mpfr=/opt/local/ --with-mpc=/opt/local/
--with-libiconv-prefix=/opt/local --with-newlib
My host is running macOS 10.14.6. gcc and g++ build successfully, but while
building libstdc++v3 I get:
.../libstdc++-v3/include/chrono:544:7: internal compiler error: in
vague_linkage_p, at cp/decl2.c:2041
This is with code freshly fetched with git today.
