2022-09-30Hexagon (target/hexagon) Change decision to set pkt_has_store_s[01]Taylor Simpson
We have found cases where pkt_has_store_s[01] is set incorrectly. This leads to generating an unnecessary store that is left over from a previous packet. Add an attribute to determine if an instruction is a scalar store The attribute is attached to the fSTORE macro (hex_common.py) Update the logic in decode.c that sets pkt_has_store_s[01] Signed-off-by: Taylor Simpson <tsimpson@quicinc.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20220920080746.26791-4-tsimpson@quicinc.com>
2022-09-30Hexagon (target/hexagon) add instruction attributes from archlibTaylor Simpson
The imported files from the architecture library have added some instruction attributes. Some of these will be used in a subsequent patch for determing the size of a store.

2021-10-28Hexagon (target/hexagon) put writes to USR into temp until commitTaylor Simpson
Change SET_USR_FIELD to write to hex_new_value[HEX_REG_USR] instead of hex_gpr[HEX_REG_USR]. Then, we need code to mark the instructions that can set implicitly set USR - Macros added to hex_common.py - A_FPOP added in translate.c Test case added in tests/tcg/hexagon/overflow.c Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Taylor Simpson <tsimpson@quicinc.com>
