This patch series is a significant update for the Hexagon target
The first 10 patches address feedback from Richard Henderson
<richard.hender...@linaro.org>
The next 6 patches add the remaining instructions for the Hexagon
scalar core
The patches are logically independent but are organized as a series to
avoid potential confilcts if they are merged out of order.
Note that the new test cases require an update toolchain/container.
*** Changes in v2 ***
Address feedback from Richard Henderson <richard.hender...@linaro.org>
Break utility function (arch.c) changes into 2 separate patches
Change bit-reverse addressing from TCG generation to helper
Change loadalign[bh] to use shift+deposit
Remove fGET_TCG_tmp
Remove unneeded ireg and tmp variables
Remove unused one variable from gen_log_predicated_reg_write
Rename gen_exception to gen_exception_raw
Remove unreachable tcg_gen_exit_tb

Remove TARGET_HEXAGON code from parts_silence_nan
Change roundrom to uint8_t in arch_recip_lookup and arch_invsqrt_lookup
Rewrite fGEN_TCG_addp_c/fGEN_TCG_subp_c using tcg_gen_add2_i64
Remove gen_carry_from_add64()
Break "instructions with multiple definitions" into multiple patches
Fix fINSERT_RANGE macro
Expand macros inside GET_EA_pci, GET_EA_pcr
