Subject: [PATCH 00/11] softfloat: Improve denormal handling
Date: Wed, 26 May 2021 21:13:54 -0700 [thread overview]
Message-ID: <20210527041405.391567-1-richard.henderson@linaro.org> (raw)
This attempts to fix the x86 denormal-exception flag, which is the
inverse of the existing float_flag_input_denormal flag. I have not
created a new test case for this yet, fwiw.
While auditing all uses of float_flag_*_denormal, I found some errors
in target/rx and target/mips.
This is based on my current softfloat conversion for floatx80:
Based-on: <20210525150706.294968-1-richard.henderson@linaro.org>

Richard Henderson (11):
softfloat: Rename float_flag_input_denormal to
float_flag_iflush_denormal
softfloat: Rename float_flag_output_denormal to
float_flag_oflush_denormal
softfloat: Introduce float_flag_inorm_denormal
softfloat: Introduce float_flag_result_denormal
target/i386: Use float_flag_inorm_denormal
target/rx: Handle the FPSW.DN bit in helper_set_fpsw
target/rx: Use FloatRoundMode in helper_set_fpsw
target/rx: Fix setting of FPSW.CE
target/mips: Drop inline markers from msa_helper.c
target/mips: Do not check MSACSR_FS_MASK in update_msacsr
target/mips: Drop denormal operand to update_msacsr
