Bug ID: 91269
Summary: sparc64-gcc fails to build glibc (-fcall-used-g6) on
niagara4: Assembler messages: Error: Illegal operands
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: slyfox at inbox dot ru
Target Milestone: ---
Original failure happens when glibc is built as:
../glibc/configure --prefix=/usr --build=x86_64-pc-linux-gnu
--host=sparc64-unknown-linux-gnu CFLAGS="-O2 -mcpu=niagara4 -pipe" && make
Single file iso-2022-jp-3.c fails to build as:
