Subject: [PATCH 0/3] Improve x86 rounding implementation when FE_INEXACT trap is enabled
Date: Wed, 3 Apr 2024 16:39:16 -0300 [thread overview]
Message-ID: <20240403193919.1533786-1-adhemerval.zanella@linaro.org> (raw)
Some x86 rounding implementation that uses 387 raises invalid
floating point exceptions when traps are enabled. This is a GNU
extension outside the scope of the C standard.
Adhemerval Zanella (3):
math: math: x86 ceill traps when FE_INEXACT is enabled (BZ 31600)
math: math: x86 floor traps when FE_INEXACT is enabled (BZ 31601)
math: math: x86 trunc traps when FE_INEXACT is enabled (BZ 31603)
