At present, it can run into glibc _init_malloc(), but cause assertion,
which should be fixed, next.
Since it already has quite a few of code, so send patches firstly, and
next, continue fixing the issue.
Chen Gang (10):
linux-user: tilegx: Firstly add architecture related features
linux-user: Support tilegx architecture in linux-user
linux-user/syscall.c: conditionalize syscalls which are not defined in
tilegx
target-tilegx: Add opcode basic implementation from Tilera Corporation
target-tilegx/opcode_tilegx.h: Modify it to fit qemu using
target-tilegx: Add special register information from Tilera
Corporation
target-tilegx: Add cpu basic features for linux-user
target-tilegx: Add helper features for linux-user
target-tilegx: Generate tcg instructions to execute to _init_malloc in
glib
target-tilegx: Add TILE-Gx building files

Then there's no need for a switch, nor a need for a confusing TILEGX_EXCP_OPCODE_UNKNOWN path. > +static void gen_exch(struct DisasContext *dc, > + uint8_t rdst, uint8_t rsrc, uint8_t rsrcb, int excp) > +{ > + const char *prefix, *width; > + > + switch (excp) { > + case TILEGX_EXCP_OPCODE_EXCH4: > + prefix = ""; > + width = "4"; > + break; > + case TILEGX_EXCP_OPCODE_EXCH: > + prefix = ""; > + width = ""; > + break; > + case TILEGX_EXCP_OPCODE_CMPEXCH4: > + prefix = "cmp"; > + width = "4"; > + break; > + case TILEGX_EXCP_OPCODE_CMPEXCH: > + prefix = "cmp"; > + width = ""; > + break; > + default: > + dc->exception = TILEGX_EXCP_OPCODE_UNKNOWN; > + return; > + } Likewise. > +static void gen_v1cmpeqi(struct DisasContext *dc, > + uint8_t rdst, uint8_t rsrc, uint8_t imm8) > +{ > + int count; > + TCGv vdst = dest_gr(dc, rdst); > + TCGv tmp = tcg_temp_new_i64(); > + > + qemu_log_mask(CPU_LOG_TB_IN_ASM, "v1cmpeqi r%d, r%d, %d\n", > + rdst, rsrc, imm8); > + > + tcg_gen_movi_i64(vdst, 0); > + > + for (count = 0; count < 8; count++) { > + tcg_gen_shri_i64(tmp, load_gr(dc, rsrc), (8 - count - 1) * 8); > + tcg_gen_andi_i64(tmp, tmp, 0xff); > + tcg_gen_setcondi_i64(TCG_COND_EQ, tmp, tmp, imm8); > + tcg_gen_or_i64(vdst, vdst, tmp); > + tcg_gen_shli_i64(vdst, vdst, 8); For all of these vector instructions, I would encourage you to use helpers to extract and insert values. Extraction has little choice but to use a shift and a mask, as you use here. But insertion can use tcg_gen_deposit_i64. I think that is a lot easier to reason with than your construction here which sequentially shifts vdst. E.g. static inline void extract_v1(TCGv out, TCGv in, unsigned byte) { tcg_gen_shri_i64(out, in, byte * 8); tcg_gen_ext8u_i64(out, out); } static inline void insert_v1(TCGv out, TCGv in, unsigned byte) { tcg_gen_deposit_i64(out, out, in, byte * 8, 8); } This loop then becomes TCGv vsrc = load_gr(dc, src); for (count = 0; count < 8; ++count) { extract_v1(tmp, vsrc, count); tcg_gen_setcondi_i64(TCG_COND_EQ, tmp, tmp, imm8); insert_v1(vdst, tmp, count); } > +static void gen_v1int_l(struct DisasContext *dc, > + uint8_t rdst, uint8_t rsrc, uint8_t rsrcb) > +{ > + int count; > + TCGv vdst = dest_gr(dc, rdst); > + TCGv tmp = tcg_temp_new_i64(); > + > + qemu_log_mask(CPU_LOG_TB_IN_ASM, "v1int_l r%d, r%d, r%d\n", > + rdst, rsrc, rsrcb); > + > + tcg_gen_movi_i64(vdst, 0); > + for (count = 0; count < 4; count++) { > + > + tcg_gen_shli_i64(vdst, vdst, 8); > + > + tcg_gen_shri_i64(tmp, load_gr(dc, rsrc), (4 - count - 1) * 8); > + tcg_gen_andi_i64(tmp, tmp, 0xff); > + tcg_gen_or_i64(vdst, vdst, tmp); > + tcg_gen_shli_i64(vdst, vdst, 8); > + > + tcg_gen_shri_i64(tmp, load_gr(dc, rsrcb), (4 - count - 1) * 8); > + tcg_gen_andi_i64(tmp, tmp, 0xff); > + tcg_gen_or_i64(vdst, vdst, tmp); > + } > + tcg_temp_free_i64(tmp); TCGv vsrc = load_gr(dc, rsrc); TCGv vsrcb = load_gr(dc, rsrcb); for (count = 0; count < 4; ++count) { extract_v1(tmp, vsrc, count); insert_v1(vdst, tmp, count * 2); extract_v1(tmp, vsrcb, count); insert_v1(vdst, tmp, count * 2 + 1); } > +} > + > +/* > + * Functional Description > + * > + * uint64_t output = 0; > + * uint32_t counter; > + * for (counter = 0; counter < (WORD_SIZE / 32); counter++) > + * { > + * bool asel = ((counter & 1) == 1); > + * int in_sel = 0 + counter / 2; > + * int32_t srca = get4Byte (rf[SrcA], in_sel); > + * int32_t srcb = get4Byte (rf[SrcB], in_sel); > + * output = set4Byte (output, counter, (asel ? srca : srcb)); > + * } > + * rf[Dest] = output; > +*/ > + > +static void gen_v4int_l(struct DisasContext *dc, > + uint8_t rdst, uint8_t rsrc, uint8_t rsrcb) > +{ > + TCGv vdst = dest_gr(dc, rdst); > + TCGv tmp = tcg_temp_new_i64(); > + > + qemu_log_mask(CPU_LOG_TB_IN_ASM, "v4int_l r%d, r%d, r%d\n", > + rdst, rsrc, rsrcb); > + > + tcg_gen_andi_i64(vdst, load_gr(dc, rsrc), 0xffffffff); > + tcg_gen_shli_i64(vdst, vdst, 8); > + tcg_gen_andi_i64(tmp, load_gr(dc, rsrcb), 0xffffffff); > + tcg_gen_or_i64(vdst, vdst, tmp); And herein is a bug, that I'd hope using the helper functions would avoid: you shift by 8 instead of 32.
