Bug ID: 10551
Summary: PowerPC SPE and Musl
Product: buildroot
Version: 2017.08
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: sigurd.segtnan at kongsberg.com
CC: buildroot at uclibc.org
Target Milestone: ---
Created attachment 7411
--> https://bugs.busybox.net/attachment.cgi?id=7411&action=edit
diff for package/gcc/gcc.mk (and Config.in in toolchain)
Musl is not supported for PowerPC SPE according to
toolchain/toolchain-buildroot/Config.in line 74: "depens on !BR2_powerpc_SPE #
not supported, build breaks". This breakage may be due the
"--with-long-double-128" in package/gcc/gcc.mk, since we have not experienced
any build breakage when we changed lines 241-245 to
ifeq ($(BR2_powerpc_SPE),y)
ifeq ($(BR2_TOOLCHAIN_USES_MUSL),n)
HOST_GCC_COMMON_CONF_OPTS += \
--enable-e500_double \
--with-long-double-128
endif
else
HOST_GCC_COMMON_CONF_OPTS += \
--enable-e500_double \
--with-long-double-64 \
--enable-secureplt
endif
We have used this without problems since buildroot 2016.05 (tested with gcc 6.x
and gcc 7.x).
