2015-09-14target-arm: Introduce DisasCompareRichard Henderson2-46/+78
Split arm_gen_test_cc into 3 functions, so that it can be reused for non-branch TCG comparisons.

2015-09-14target-arm: Share all common TCG temporariesRichard Henderson3-27/+13
This is a bug fix for aarch64. At present, we have branches using the 32-bit (translate.c) versions of cpu_[NZCV]F, but we set the flags using the 64-bit (translate-a64.c) versions of cpu_[NZCV]F. From the view of the TCG code generator, these are unrelated variables. The bug is hard to see because we currently only read these variables from branches, and upon reaching a branch TCG will first spill live variables and then reload the arguments of the branch. Since the 32-bit versions were never live until reaching the branch, we'd re-read the data that had just been spilled from the 64-bit versions. There is currently no such problem with the cpu_exclusive_* variables, but there's no point in tempting fate.

2015-09-13target-sh4: improve shad instructionAurelien Jarno1-31/+22
The SH4 shad instruction can shift in both direction, depending on the sign of the shift. This is currently implemented using branches, which is not really efficient and prevents the optimizer to do its job. In practice it is often used with a constant loaded in a register just before. Simplify the implementation by computing both the value shifted to the left and to the right, and then selecting the correct one with a movcond. As with a negative value the shift amount can go up to 32 which is undefined, we shift the value in two steps.

2015-09-13target-sh4: improve cmp/str instructionAurelien Jarno1-12/+5
Instead of testing bytes one by one, we can use the following trick from https://graphics.stanford.edu/~seander/bithacks.html: haszero(v) = (v - 0x01010101) & ~v & 0x80808080 The subexpression v - 0x01010101, evaluates to a high bit set in any byte whenever the corresponding byte in v is zero or greater than 0x80. The sub-expression ~v & 0x80808080 evaluates to high bits set in bytes where the byte of v doesn't have its high bit set (so the byte was less than 0x80). Finally, by ANDing these two sub-expressions the result is the high bits set where the bytes in v were zero, since the high bits set due to a value greater than 0x80 in the first sub-expression are masked off by the second.

This is set to true when the index is for an instruction fetch translation. The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS acessors. All targets ignore it for now, and all other callers pass "false". This will allow targets who wish to split the mmu index between instruction and data accesses to do so. A subsequent patch will do just that for PowerPC.

Whereas muldiv64 is: uint64_t muldiv64(uint64_t a, uint32_t b, uint32_t c) So we loose 3 bits of timeout. Swapping get_ticks_per_sec() and timeout fixes it.
