From aacd348637e38795dd7ae3c7c8c908d8c0cd24fd Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 27 Feb 2014 22:03:25 -0500 Subject: rename superh port to "sh" for consistency linux, gcc, etc. all use "sh" as the name for the superh arch. there was already some inconsistency internally in musl: the dynamic linker was searching for "ld-musl-sh.path" as its path file despite its own name being "ld-musl-superh.so.1". there was some sentiment in both directions as to how to resolve the inconsistency, but overall "sh" was favored. --- src/fenv/sh/fenv.s | 74 ++++++++++++++++++++++++++++++++++++++++++++++++++ src/fenv/superh/fenv.s | 74 -------------------------------------------------- 2 files changed, 74 insertions(+), 74 deletions(-) create mode 100644 src/fenv/sh/fenv.s delete mode 100644 src/fenv/superh/fenv.s (limited to 'src/fenv') diff --git a/src/fenv/sh/fenv.s b/src/fenv/sh/fenv.s new file mode 100644 index 00000000..7f5c6277 --- /dev/null +++ b/src/fenv/sh/fenv.s @@ -0,0 +1,74 @@ +.global fegetround +.type fegetround, @function +fegetround: + sts fpscr, r0 + rts + and #3, r0 + +.global __fesetround +.type __fesetround, @function +__fesetround: + sts fpscr, r0 + or r4, r0 + lds r0, fpscr + rts + mov #0, r0 + +.global fetestexcept +.type fetestexcept, @function +fetestexcept: + sts fpscr, r0 + and r4, r0 + rts + and #0x7c, r0 + +.global feclearexcept +.type feclearexcept, @function +feclearexcept: + mov r4, r0 + and #0x7c, r0 + not r0, r4 + sts fpscr, r0 + and r4, r0 + lds r0, fpscr + rts + mov #0, r0 + +.global feraiseexcept +.type feraiseexcept, @function +feraiseexcept: + mov r4, r0 + and #0x7c, r0 + sts fpscr, r4 + or r4, r0 + lds r0, fpscr + rts + mov #0, r0 + +.global fegetenv +.type fegetenv, @function +fegetenv: + sts fpscr, r0 + mov.l r0, @r4 + rts + mov #0, r0 + +.global fesetenv +.type fesetenv, @function +fesetenv: + mov r4, r0 + cmp/eq #-1, r0 + bf 1f + + ! the default environment is complicated by the fact that we need to + ! preserve the current precision bit, which we do not know a priori + sts fpscr, r0 + mov #8, r1 + swap.w r1, r1 + bra 2f + and r1, r0 + +1: mov.l @r4, r0 ! non-default environment +2: lds r0, fpscr + rts + mov #0, r0 diff --git a/src/fenv/superh/fenv.s b/src/fenv/superh/fenv.s deleted file mode 100644 index 7f5c6277..00000000 --- a/src/fenv/superh/fenv.s +++ /dev/null @@ -1,74 +0,0 @@ -.global fegetround -.type fegetround, @function -fegetround: - sts fpscr, r0 - rts - and #3, r0 - -.global __fesetround -.type __fesetround, @function -__fesetround: - sts fpscr, r0 - or r4, r0 - lds r0, fpscr - rts - mov #0, r0 - -.global fetestexcept -.type fetestexcept, @function -fetestexcept: - sts fpscr, r0 - and r4, r0 - rts - and #0x7c, r0 - -.global feclearexcept -.type feclearexcept, @function -feclearexcept: - mov r4, r0 - and #0x7c, r0 - not r0, r4 - sts fpscr, r0 - and r4, r0 - lds r0, fpscr - rts - mov #0, r0 - -.global feraiseexcept -.type feraiseexcept, @function -feraiseexcept: - mov r4, r0 - and #0x7c, r0 - sts fpscr, r4 - or r4, r0 - lds r0, fpscr - rts - mov #0, r0 - -.global fegetenv -.type fegetenv, @function -fegetenv: - sts fpscr, r0 - mov.l r0, @r4 - rts - mov #0, r0 - -.global fesetenv -.type fesetenv, @function -fesetenv: - mov r4, r0 - cmp/eq #-1, r0 - bf 1f - - ! the default environment is complicated by the fact that we need to - ! preserve the current precision bit, which we do not know a priori - sts fpscr, r0 - mov #8, r1 - swap.w r1, r1 - bra 2f - and r1, r0 - -1: mov.l @r4, r0 ! non-default environment -2: lds r0, fpscr - rts - mov #0, r0 -- cgit v1.2.1
