[PATCH] Add micromips support to the MIPS simulator
2015-09-25 Andrew Bennett <andrew.bennett@imgtec.com> Ali Lown <ali.lown@imgtec.com> sim/common/ * sim-bits.h (EXTEND6): New macro. (EXTEND12): New macro. (EXTEND25): New macro. sim/mips/ * Makefile.in (tmp-micromips): New rule. (tmp-mach-multi): Add support for micromips. * configure.ac (mips*-sde-elf* | mips*-mti-elf*): Made a multi sim that works for both mips64 and micromips64. (mipsisa32r2*-*-*): Made a multi sim that works for mips32 and micromips32. Add build support for micromips. * dsp.igen (do_ph_s_absq, do_w_s_absq, do_qb_s_absq, do_addsc, do_addwc, do_bitrev, do_extpv, do_extrv, do_extrv_s_h, do_insv, do_lxx do_modsub, do_mthlip, do_mulsaq_s_w_ph, do_ph_packrl, do_qb_pick do_ph_pick, do_qb_ph_precequ, do_qb_ph_preceu, do_w_preceq do_w_ph_precrq, do_ph_qb_precrq, do_w_ph_rs_precrq do_qb_w_raddu, do_rddsp, do_repl, do_shilov, do_ph_shl, do_qb_shl do_w_s_shllv, do_ph_shrlv, do_w_r_shrav, do_wrdsp, do_qb_shrav, do_append, do_balign, do_ph_w_mulsa, do_ph_qb_precr, do_prepend): New functions. Refactored instruction code to use these functions. * dsp2.igen: Refactored instruction code to use the new functions. * interp.c (decode_coproc): Refactored to work with any instruction encoding. (isa_mode): New variable (RSVD_INSTRUCTION): Changed to 0x00000039. * m16.igen (BREAK16): Refactored instruction to use do_break16. (JALX32): Add mips32, mips64, mips32r2 and mips64r2 models. * micromips.dc: New file. * micromips.igen: New file. * micromips16.dc: New file. * micromipsdsp.igen: New file. * micromipsrun.c: New file. * mips.igen (do_swc1): Changed to work with any instruction encoding.

Refactored instruction code to use these functions. (RSVD): Changed to use new reserved instruction. (loadstore_ea, not_word_value, unpredictable, check_mt_hilo, check_mf_hilo, check_mult_hilo, check_div_hilo, check_u64, do_luxc1_32, do_sdc1, do_suxc1_32, check_fmt_p, check_fpu, do_load_double, do_store_double): Added micromips32 and micromips64 models.

(sim_state): Add isa_mode field. sim/testsuite/sim/mips/ * basic.exp (run_micromips_test, run_sim_tests): New functions Add support for micromips tests. * hilo-hazard-4.s: New file. * testutils.inc (_dowrite): Changed reserved instruction encoding. (writemsg): Moved the la and li instructions before the data they are assigned to, which prevents a bug where MIPS32 relocations are used instead of micromips relocations when building for micromips.
