2024-08-21target/i386: Fix carry flag for BLSIRichard Henderson
BLSI has inverted semantics for C as compared to the other two BMI1 instructions, BLSMSK and BLSR. Introduce CC_OP_BLSI* for this purpose.

2024-08-07Hexagon: fix F2_conv_* instructions for negative zeroMatheus Tavares Bernardino
The implementation for these instructions handles -0 as an invalid float point value, whereas the Hexagon hardware considers it the same as +0 (which is valid). Let's fix that and add a regression test.

2024-07-30tests/tcg: move test plugins into tcg subdirAlex Bennée
You cannot use plugins without TCG enabled so it doesn't make sense to have them separated off in the test directory structure. While we are at it rename the directory to plugins to reflect the plural nature of the directory and match up with contrib/plugins.

At 09a7e7db0f (Hexagon (target/hexagon) Remove uses of op_regs_generated.h.inc, 2024-03-06), we've changed the logic of check_new_value() to use the new pre-calculated packet->insn[...].dest_idx instead of calculating the index on the fly using opcode_reginfo[...]. The dest_idx index is calculated roughly like the following: for reg in iset[tag]["syntax"]: if reg.is_written(): dest_idx = regno break Thus, we take the first register that is writtable. Before that, however, we also used to follow an alphabetical order on the register type: 'd', 'e', 'x', and 'y'. No longer following that makes us select the wrong register index and the HVX store new instruction does not update the memory like expected.

2024-03-29tcg/optimize: Fix sign_mask for logical right-shiftRichard Henderson
The 'sign' computation is attempting to locate the sign bit that has been repeated, so that we can test if that bit is known zero. That computation can be zero if there are no known sign repetitions.
