From 9250e6610fdb0f3a6f238d2813e319a41fb7a810 Mon Sep 17 00:00:00 2001 From: "Gabriel F. T. Gomes" Date: Mon, 27 May 2019 15:21:22 -0300 Subject: powerpc: Fix build failures with current GCC Since GCC commit 271500 (svn), also known as the following commit on the git mirror: commit 61edec870f9fdfb5df3fa4e40f28cbaede28a5b1 Author: amodra Date: Wed May 22 04:34:26 2019 +0000 [RS6000] Don't pass -many to the assembler glibc builds are failing when an assembly implementation does not declare the correct '.machine' directive, or when no such directive is declared at all. For example, when a POWER6 instruction is used, but '.machine power6' is not declared, the assembler will fail with an error similar to the following: ../sysdeps/powerpc/powerpc64/power8/strcmp.S: Assembler messages: 24 ../sysdeps/powerpc/powerpc64/power8/strcmp.S:55: Error: unrecognized opcode: `cmpb' This patch adds '.machine powerN' directives where none existed, as well as it updates '.machine power7' directives on POWER8 files, because the minimum binutils version required to build glibc (binutils 2.25) now provides this machine version. It also adds '-many' to the assembler command used to build tst-set_ppr.c. Tested for powerpc, powerpc64, and powerpc64le, as well as with build-many-glibcs.py for powerpc targets.
