Hi Carl, While digging through the manual to figure out if we were really doing the right thing raising the fp exception, I found the fpu exception state machine. I'm not sure it's worth emulating the fp_exception_pending state, but it's certainly easy enough to emulate the fp_executing/fp_exception states.
In addition, this simplifies the implementation of STDFQ, restricts FQ to sparc32 system mode, and handles migration. Would you please double-check this against your Solaris images? r~ Carl Hauser (2): target/sparc: Add FQ and FSR.QNE target/sparc: Populate sparc32 FQ when raising fp exception Richard Henderson (4): target/sparc: Restrict STQF to sparcv9 target/sparc: Add FSR_QNE to tb_flags target/sparc: Implement STDFQ target/sparc: Add gen_trap_if_nofpu_fpexception target/sparc/cpu.h | 30 ++++++++- target/sparc/fop_helper.c | 4 ++ target/sparc/int32_helper.c | 32 ++++----- target/sparc/machine.c | 25 +++++++ target/sparc/translate.c | 126 ++++++++++++++++++++++++++---------- target/sparc/insns.decode | 4 +- 6 files changed, 169 insertions(+), 52 deletions(-) -- 2.43.0
