2023-02-21target/i386/gdbstub: Fix a bug about order of FPU stack in 'g' packets.TaiseiIto1-1/+3
Before this commit, when GDB attached an OS working on QEMU, order of FPU stack registers printed by GDB command 'info float' was wrong. There was a bug causing the problem in 'g' packets sent by QEMU to GDB. The packets have values of registers of machine emulated by QEMU containing FPU stack registers. There are 2 ways to specify a x87 FPU stack register. The first is specifying by absolute indexed register names (R0, ..., R7). The second is specifying by stack top relative indexed register names (ST0, ..., ST7). Values of the FPU stack registers should be located in 'g' packet and be ordered by the relative index. But QEMU had located these registers ordered by the absolute index. After this commit, when QEMU reads registers to make a 'g' packet, QEMU specifies FPU stack registers by the relative index. Then, the registers are ordered correctly in the packet. As a result, GDB, the packet receiver, can print FPU stack registers in the correct order.

2023-02-11target/i386: fix ADOX followed by ADCXPaolo Bonzini1-9/+11
When ADCX is followed by ADOX or vice versa, the second instruction's carry comes from EFLAGS and the condition codes use the CC_OP_ADCOX operation. Retrieving the carry from EFLAGS is handled by this bit of gen_ADCOX: tcg_gen_extract_tl(carry_in, cpu_cc_src, ctz32(cc_op == CC_OP_ADCX ? CC_C : CC_O), 1); Unfortunately, in this case cc_op has been overwritten by the previous "if" statement to CC_OP_ADCOX. This works by chance when the first instruction is ADCX; however, if the first instruction is ADOX, ADCX will incorrectly take its carry from OF instead of CF. Fix by moving the computation of the new cc_op at the end of the function. The included exhaustive test case fails without this patch and passes afterwards. Because ADCX/ADOX need not be invoked through the VEX prefix, this regression bisects to commit 16fc5726a6e2 ("target/i386: reimplement 0x0f 0x38, add AVX", 2022-10-18). However, the mistake happened a little earlier, when BMI instructions were rewritten using the new decoder framework.

2023-02-08target/tricore: Fix OPC2_32_RRRR_DEXTRBastian Koppelmann1-3/+12
if cpu_gpr_d[r3] == 0 then we were shifting the lower register to the right by 32 which is undefined behaviour. In this case the TriCore would do nothing an just return the higher register cpu_reg_d[r1]. We fixed that by detecting whether cpu_gpr_d[r3] was zero and cleared the lower register.

2023-02-07target/riscv: fix for virtual instr exceptionDeepak Gupta1-0/+1
commit fb3f3730e4 added mechanism to generate virtual instruction exception during instruction decode when virt is enabled. However in some situations, illegal instruction exception can be raised due to state of CPU. One such situation is implementing branch tracking. [1] An indirect branch if doesn't land on a landing pad instruction, then cpu must raise an illegal instruction exception. Implementation would raise such expcetion due to missing landing pad inst and not due to decode. Thus DisasContext must have `virt_inst_excp` initialized to false during DisasContxt initialization for TB.
