* target/ppc: Fix xvcmp* clearing FI bitVíctor Colombo2022-10-171-1/+0Star
| | | | | | | | | | | | | | | | | Vector instructions in general are not supposed to change the FI bit. However, xvcmp* instructions are calling gen_helper_float_check_status, which is leading to a cleared FI flag where it should be kept unchanged. As helper_float_check_status only affects inexact, overflow and underflow, and the xvcmp* instructions don't change these flags, this issue can be fixed by removing the call to helper_float_check_status. By doing this, the FI bit in FPSCR will be preserved as expected. Fixes: 00084a25adf ("target/ppc: introduce separate VSX_CMP macro for xvcmp* instructions") Signed-off-by: Víctor Colombo <victor.colombo@eldorado.org.br> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20221005121551.27957-1-victor.colombo@eldorado.org.br> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com>
* target/ppc: Merge fsqrt and fsqrts helpersVíctor Colombo2022-09-201-2/+2
| | | | | | | | | | | | These two helpers are almost identical, differing only by the softfloat operation it calls. Merge them into one using a macro. Also, take this opportunity to capitalize the helper name as we moved the instruction to decodetree in a previous patch.

| | | | | | | | | | | | | | | | | | | | Implement the following PowerISA v3.1 instructions: xxmfacc: VSX Move From Accumulator xxmtacc: VSX Move To Accumulator xxsetaccz: VSX Set Accumulator to Zero The PowerISA 3.1 mentions that for the current version of the architecture, "the hardware implementation provides the effect of ACC[i] and VSRs 4*i to 4*i + 3 logically containing the same data" and "The Accumulators introduce no new logical state at this time" (page 501). For now it seems unnecessary to create new structures, so this patch just uses ACC[i] as VSRs 4*i to 4*i+3 and therefore move to and from accumulators are no-ops.
