From 9b0fcb441a44456c7b071c7cdaf90403f81ec05a Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Fri, 6 Sep 2013 18:35:55 +0000 Subject: math: remove STRICT_ASSIGN macro gcc did not always drop excess precision according to c99 at assignments before version 4.5 even if -std=c99 was requested which caused badly broken mathematical functions on i386 when FLT_EVAL_METHOD!=0 but STRICT_ASSIGN was not used consistently and it is worked around for old compilers with -ffloat-store so it is no longer needed the new convention is to get the compiler respect c99 semantics and when excess precision is not harmful use float_t or double_t or to specialize code using FLT_EVAL_METHOD --- src/math/__rem_pio2f.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/math/__rem_pio2f.c') diff --git a/src/math/__rem_pio2f.c b/src/math/__rem_pio2f.c index 198ee91b..5bdeb529 100644 --- a/src/math/__rem_pio2f.c +++ b/src/math/__rem_pio2f.c @@ -44,7 +44,7 @@ int __rem_pio2f(float x, double *y) /* 25+53 bit pi is good enough for medium size */ if (ix < 0x4dc90fdb) { /* |x| ~< 2^28*(pi/2), medium size */ /* Use a specialized rint() to get fn.
