2015-10-19tcg/mips: Support r6 SEL{NE, EQ}Z instead of MOVN/MOVZJames Hogan1-6/+37
Extend MIPS movcond implementation to support the SELNEZ/SELEQZ instructions introduced in MIPS r6 (where MOVN/MOVZ have been removed). Whereas the "MOVN/MOVZ rd, rs, rt" instructions have the following semantics: rd = [!]rt ? rs : rd The "SELNEZ/SELEQZ rd, rs, rt" instructions are slightly different: rd = [!]rt ? rs : 0 First we ensure that if one of the movcond input values is zero that it comes last (we can swap the input arguments if we invert the condition). This is so that it can exactly match one of the SELNEZ/SELEQZ instructions and avoid the need to emit the other one. Otherwise we emit the opposite instruction first into a temporary register, and OR that into the result: SELNEZ/SELEQZ TMP1, v2, c1 SELEQZ/SELNEZ ret, v1, c1 OR ret, ret, TMP1 Which does the following: ret = cond ? v1 : v2 Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: James Hogan <james.hogan@imgtec.com> Signed-off-by: Richard Henderson <rth@twiddle.net> Message-Id: <1443788657-14537-7-git-send-email-james.hogan@imgtec.com>
2015-10-19tcg/mips: Support r6 multiply/divide encodingsJames Hogan2-3/+43
MIPSr6 adds several new integer multiply, divide, and modulo instructions, and removes several pre-r6 encodings, along with the HI/LO registers which were the implicit operands of some of those instructions. Update TCG to use the new instructions when built for r6. The new instructions actually map much more directly to the TCG ops, as they only provide a single 32-bit half of the result and in a normal general purpose register instead of HI or LO. The mulu2_i32 and muls2_i32 operations are no longer appropriate for r6, so they are removed from the TCG opcode table. This is because they would need to emit two separate host instructions anyway (for the high and low half of the result), which TCG can arrange automatically for us in the absense of mulu2_i32/muls2_i32 by splitting it into mul_i32 and mul*h_i32 TCG ops.

MIPSr6 encodes JR as JALR with zero as the link register, and the pre-r6 JR encoding is removed. Update TCG to use the new encoding when built for r6. We still use the old encoding for pre-r6, so as not to confuse return prediction stack hardware which may detect only particular encodings of the return instruction.

2015-10-19tcg/ppc: Revise goto_tb implementationRichard Henderson1-11/+38
Restrict the size of code_gen_buffer to 2GB on ppc64, which lets us assert that everything is reachable with addis+addi from tb_ret_addr. This lets us use a max of 4 insns for goto_tb instead of 7. Emit the indirect branch portion of goto_tb up front, which means we only have to update two insns to update any link.

We currently pre-compute an worst case code size for any TB, which works out to be 122kB. Since the average TB size is near 1kB, this wastes quite a lot of storage.

2015-09-19tcg/mips: Fix clobbering of qemu_ld inputsJames Hogan1-11/+15
The MIPS TCG backend implements qemu_ld with 64-bit targets using the v0 register (base) as a temporary to load the upper half of the QEMU TLB comparator (see line 5 below), however this happens before the input address is used (line 8 to mask off the low bits for the TLB comparison, and line 12 to add the host-guest offset). If the input address (addrl) also happens to have been placed in v0 (as in the second column below), it gets clobbered before it is used. addrl in t2 addrl in v0 1 srl a0,t2,0x7 srl a0,v0,0x7 2 andi a0,a0,0x1fe0 andi a0,a0,0x1fe0 3 addu a0,a0,s0 addu a0,a0,s0 4 lw at,9136(a0) lw at,9136(a0) set TCG_TMP0 (at) 5 lw v0,9140(a0) lw v0,9140(a0) set base (v0) 6 li t9,-4093 li t9,-4093 7 lw a0,9160(a0) lw a0,9160(a0) set addend (a0) 8 and t9,t9,t2 and t9,t9,v0 use addrl 9 bne at,t9,0x836d8c8 bne at,t9,0x836d838 use TCG_TMP0 10 nop nop 11 bne v0,t8,0x836d8c8 bne v0,a1,0x836d838 use base 12 addu v0,a0,t2 addu v0,a0,v0 use addrl, addend 13 lw t0,0(v0) lw t0,0(v0) Fix by using TCG_TMP0 (at) as the temporary instead of v0 (base), pushing the load on line 5 forward into the delay slot of the low comparison (line 10).
