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/log1p.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/math/log1p.c') diff --git a/src/math/log1p.c b/src/math/log1p.c index 9bed63c2..a71ac423 100644 --- a/src/math/log1p.c +++ b/src/math/log1p.c @@ -122,7 +122,7 @@ double log1p(double x) return x+x; if (k != 0) { if (hx < 0x43400000) { - STRICT_ASSIGN(double, u, 1.0 + x); + u = 1 + x; GET_HIGH_WORD(hu, u); k = (hu>>20) - 1023; c = k > 0 ? 1.0-(u-x) : x-(u-1.0); /* correction term */ -- cgit v1.2.1
