Define the LDBL_PREC to be the number of significant bits in a long double's mantissa. 2005-03-07 04:53:36 +00:00			`# $FreeBSD$`

Add symbol versioning to libm. 2006-03-27 23:59:45 +00:00			`SYM_MAPS += ${.CURDIR}/arm/Symbol.map`
On armv6 access both the softfloat and, when available, the vfp to get and set the floating-point environment. 2014-03-15 21:58:07 +00:00
Support armv7 builds for userland Make armv7 as a new MACHINE_ARCH. Copy all the places we do armv6 and add armv7 as basically an alias. clang appears to generate code for armv7 by default. armv7 hard float isn't supported by the the in-tree gcc, so it hasn't been updated to have a new default. Support armv7 as a new valid MACHINE_ARCH (and by extension TARGET_ARCH). Add armv7 to the universe build.

Fix compilation when the armv6 world is being compiled without hw floating point support. The fenv-vfp.c file overrides -mfloat-abi so it can use floating point instructions if it detects support at runtime. Make it also override -mfpu in case the user has set -mfpu=none. 2015-06-24 18:29:34 +00:00			`CFLAGS.fenv-vfp.c= -mfpu=vfp -mfloat-abi=softfp`
