From 5b9873fa7236daa522c59c2c40f85938098acfe7 Mon Sep 17 00:00:00 2001 From: Thomas Preud'homme Date: Wed, 9 Dec 2015 11:00:55 +0800 Subject: Check for 64 FP instructions availability in libm before using them Currently, double precision math functions in newlib/libm/machine/arm detect whether neon instructions can be used for double precision computation by checking the architecture version (>= 8) and the availability of floating-point instructions. However, these instructions would not be available if targeting fpv5-sp-d16 as the FPU, which by definition does not have 64bit float instructions. This patch adds a check that __ARM_FP advertises 64bit float instructions. * libm/machine/arm/s_ceil.c: Also check that 64bit FP instructions are available in the guard. * libm/machine/arm/s_floor.c: Likewise. * libm/machine/arm/s_nearbyint.c: Likewise. * libm/machine/arm/s_rint.c: Likewise. * libm/machine/arm/s_round.c: Likewise. * libm/machine/arm/s_trunc.c: Likewise. --- newlib/ChangeLog | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'newlib/ChangeLog') diff --git a/newlib/ChangeLog b/newlib/ChangeLog index de5c84b21..1524b9923 100644 --- a/newlib/ChangeLog +++ b/newlib/ChangeLog @@ -1,3 +1,13 @@ +2015-12-09 Thomas Preud'homme + + * libm/machine/arm/s_ceil.c: Also check that 64bit FP instructions are + available in the guard. + * libm/machine/arm/s_floor.c: Likewise. + * libm/machine/arm/s_nearbyint.c: Likewise. + * libm/machine/arm/s_rint.c: Likewise. + * libm/machine/arm/s_round.c: Likewise. + * libm/machine/arm/s_trunc.c: Likewise. + 2015-12-08 Corinna Vinschen * libc/stdio/fclose.c (_fclose_r): Make _flockfile/_funlockfile calls -- cgit v1.2.3
