T. Gomes" Changes since v1: - Do not try to remove -mabi=ieeelongdouble, since it hasn't been added. The removal is a residue from our initial development. -- 8< -- Some compiler versions, e.g. GCC 7, complain when -mlong-double-128 is used together with -mabi=ibmlongdouble or -mabi=ieeelongdouble, producing the following error message: cc1: error: ‘-mabi=ibmlongdouble’ requires ‘-mlong-double-128’ This patch removes -mlong-double-128 from the compilation lines that explicitly request -mabi=*longdouble. Tested for powerpc64le. --- sysdeps/ieee754/ldbl-128ibm-compat/Makefile | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/sysdeps/ieee754/ldbl-128ibm-compat/Makefile b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile index 013f2d7fc5..a7c25add7e 100644 --- a/sysdeps/ieee754/ldbl-128ibm-compat/Makefile +++ b/sysdeps/ieee754/ldbl-128ibm-compat/Makefile @@ -258,6 +258,13 @@ ldbl-extra-routines += err \ CFLAGS-ieee128-qefgcvt.c += -mabi=ieeelongdouble -Wno-psabi -mno-gnu-attribute CFLAGS-ieee128-qefgcvt_r.c += -mabi=ieeelongdouble -Wno-psabi -mno-gnu-attribute +# Remove -mlong-double-128 because it does not work correctly with +# -mabi=ibmlongdoule in some GCC versions, e.g. GCC 7. +$(foreach o,$(all-object-suffixes),$(objpfx)ieee128-qefgcvt$(o)): \ + sysdep-CFLAGS := $(filter-out -mlong-double-128, $(sysdep-CFLAGS)) +$(foreach o,$(all-object-suffixes),$(objpfx)ieee128-qefgcvt_r$(o)): \ + sysdep-CFLAGS := $(filter-out -mlong-double-128, $(sysdep-CFLAGS)) + tests-internal += tst-ibm128-warn tst-ieee128-warn tests-internal += tst-ibm128-error tst-ieee128-error tests-internal += tst-ibm128-efgcvt tst-ieee128-efgcvt @@ -334,5 +341,12 @@ ldbl-ibm128-files := $(objpfx)test-%-ibm128^ \ $(foreach r,$(ldbl-extra-routines),$(objpfx)$(r)^) \ $(foreach r,$(ldbl-extra-routines),$(objpfx)$(r)-internal^) obj-suf-foreach = $(foreach suf,$(all-object-suffixes),$(subst ^,$(suf),$(1))) + +# Remove -mlong-double-128 because it does not work correctly with +# -mabi=ibmlongdoule in some GCC versions, e.g. GCC 7. +$(call obj-suf-foreach,$(ldbl-ibm128-files)): \ + sysdep-CFLAGS := $(filter-out -mlong-double-128, $(sysdep-CFLAGS)) + +# Explicitly add -mabi=ibm-long-double to required files. $(call obj-suf-foreach,$(ldbl-ibm128-files)): \ sysdep-CFLAGS += -mabi=ibmlongdouble
