This came to light when adding hard-flaot support to ARC glibc port without hardware sqrt support causing glibc build to fail: | ../sysdeps/ieee754/dbl-64/e_sqrt.c: In function '__ieee754_sqrt': | ../sysdeps/ieee754/dbl-64/e_sqrt.c:58:54: error: unused variable 'ty' [-Werror=unused-variable] | double y, t, del, res, res1, hy, z, zz, p, hx, tx, ty, s; The reason being EMULV() macro uses the hardware provided __builtin_fma() variant, leaving temporary variables 'p, hx, tx, hy, ty' unused hence compiler warning and ensuing error. The intent of the patch was to fix that error, but EMULV is pervasive and used fair bit indirectly via othe rmacros, hence this patch. Functionally it should not result in code gen changes and if at all those would be better since the scope of those temporaries is greatly reduced now Built tested with aarch64-linux-gnu arm-linux-gnueabi arm-linux-gnueabihf hppa-linux-gnu x86_64-linux-gnu arm-linux-gnueabihf riscv64-linux-gnu-rv64imac-lp64 riscv64-linux-gnu-rv64imafdc-lp64 powerpc-linux-gnu microblaze-linux-gnu nios2-linux-gnu hppa-linux-gnu Also as suggested by Joseph [1] used --strip and compared the libs with and w/o patch and their sizes are exactly same (with gcc 9). | 624768 Jun 1 16:20 ./aarch64-linux-gnu/lib64/libm-2.31.9000.so | 382456 Jun 1 16:20 ./arm-linux-gnueabihf/lib/libm-2.31.9000.so | 611836 Jun 1 16:20 ./arm-linux-gnueabi/lib/libm-2.31.9000.so | 502556 Jun 1 16:19 ./hppa-linux-gnu/lib/libm-2.31.9000.so | 867608 Jun 1 16:19 ./microblaze-linux-gnu/lib/libm-2.31.9000.so | 724488 Jun 1 16:19 ./nios2-linux-gnu/lib/libm-2.31.9000.so | 788088 Jun 1 16:20 ./powerpc-linux-gnu/lib/libm-2.31.9000.so | 538944 Jun 1 16:20 ./riscv64-linux-gnu-rv64imafdc-lp64/lib64/lp64/libm-2.31.9000.so | 639272 Jun 1 16:20 ./riscv64-linux-gnu-rv64imac-lp64/lib64/lp64/libm-2.31.9000.so | 1321280 Jun 1 16:21 ./x86_64-linux-gnu/lib64/libm-2.31.9000.so [1] https://sourceware.org/pipermail/libc-alpha/2019-November/108267.html Signed-off-by: Vineet Gupta <vgupta@xxxxxxxxxxxx> --- sysdeps/ieee754/dbl-64/dla.h | 34 ++++--- sysdeps/ieee754/dbl-64/doasin.c | 15 ++- sysdeps/ieee754/dbl-64/dosincos.c | 70 +++++++------- sysdeps/ieee754/dbl-64/e_atan2.c | 89 +++++++++--------- sysdeps/ieee754/dbl-64/e_sqrt.c | 4 +- sysdeps/ieee754/dbl-64/s_atan.c | 56 +++++------ sysdeps/ieee754/dbl-64/s_tan.c | 148 +++++++++++++----------------- 7 files changed, 193 insertions(+), 223 deletions(-) diff --git a/sysdeps/ieee754/dbl-64/dla.h b/sysdeps/ieee754/dbl-64/dla.h index 1bbad16cf315..fd586644ef83 100644 --- a/sysdeps/ieee754/dbl-64/dla.h +++ b/sysdeps/ieee754/dbl-64/dla.h @@ -67,13 +67,15 @@ /* storage variables of type double. */ #ifdef DLA_FMS -# define EMULV(x, y, z, zz, p, hx, tx, hy, ty) \ +# define EMULV(x, y, z, zz) \ z = x * y;
