Bug ID: 220590
Summary: math/fftw3: fails to build on armv6 (729 ports
skipped)
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Keywords: needs-patch, regression
Severity: Affects Only Me
Priority: ---
Component: Individual Port(s)
Assignee: jh...@freebsd.org
Reporter: jbe...@freebsd.org
CC: freebsd-toolchain@FreeBSD.org
Assignee: jh...@freebsd.org
Flags: maintainer-feedback?(jh...@freebsd.org)
3.3.5 built fine but 3.3.6 (both pl1 and pl2) don't. Both arm* and mips* have
LDBL_PREC=53 but 3.3.6 builds fine on mips*, so the issue is Clang-related. It
seems -O1 (or higher) combined with -ffast-math makes it emit references to
sincos() rather than sin() + cos().
../libbench2/libbench2.a(verify-lib.o): In function `aphase_shift':
verify-lib.c:(.text+0x580): undefined reference to `sincos'
../libbench2/libbench2.a(verify-lib.o): In function `tf_shift':
verify-lib.c:(.text+0x1440): undefined reference to `sincos'
verify-lib.c:(.text+0x1794): undefined reference to `sincos'
