target/arm: Honour MDCR_EL2.TDE when routing exceptions due to BKPT/BRK The MDCR_EL2.TDE bit allows the exception level targeted by debug exceptions to be set to EL2 for code executing at EL0. We handle this in the arm_debug_target_el() function, but this is only used for hardware breakpoint and watchpoint exceptions, not for the exception generated when the guest executes an AArch32 BKPT or AArch64 BRK instruction. We don't have enough information for a translate-time equivalent of arm_debug_target_el(), so instead make BKPT and BRK call a special purpose helper which can do the routing, rather than the generic exception_with_syndrome helper.

This avoids slowdowns in multicore configurations caused by one core busy-waiting on a spinlock which can't possibly be unlocked until the other core has an opportunity to run. This speeds up my test case A15 dual-core boot by a factor of three (though it is still four or five times slower than a single-core boot).

DEF_HELPER_1(wfe, void, env)
target-arm: Split DISAS_YIELD from DISAS_WFE Currently we use DISAS_WFE for both WFE and YIELD instructions. This is functionally correct because at the moment both of them are implemented as "yield this CPU back to the top level loop so another CPU has a chance to run". However it's rather confusing that YIELD ends up calling HELPER(wfe), and if we ever want to implement real behaviour for WFE and SEV it's likely to trip us up. Split out the yield codepath to use DISAS_YIELD and a new HELPER(yield) function, and have HELPER(wfe) call HELPER(yield).

target/arm: Fix float16 to/from int16 The instruction "ucvtf v0.4h, v04h, #2", with input 0x8000u, overflows the intermediate float16 to infinity before we have a chance to scale the output. Use float64 as the intermediate type so that no input argument (uint32_t in this case) can overflow or round before scaling. Given the declared argument, the signed int32_t function has the same problem. When converting from float16 to integer, using u/int32_t instead of u/int16_t means that the bounding is incorrect.

There was already a get_fpstatus helper for neon for the 32 bit code. We also add an get_ahp_flag() for passing the state of the alternative FP16 format flag.

tcg: Remove stray semi-colons from target-*/helper.h During GEN_HELPER=1, these are actually stray top-level semi-colons which are technically invalid ISO C, but GCC accepts as an extension. If we added enough __extension__ markers that we could dare use -Wpedantic, we'd see warning: ISO C does not allow extra ‘;’ outside of a function This will become a hard error in the next patch, wherein those ; will appear in the middle of a data structure.

target-arm: Move Neon VUZP to helper functions Move the implementation of the Neon VUZP unzip instruction from inline code to helper functions. (At 50+ TCG ops it was well over the recommended limit for coding inline.) The helper implementations also fix the handling of the quadword version of the instruction.

target/arm: Use vector operations for saturation For same-sign saturation, we have tcg vector operations. We can compute the QC bit by comparing the saturated value against the unsaturated value.

target/arm: Add helpers for FMLAL Note that float16_to_float32 rightly squashes SNaN to QNaN. But of course pickNaNMulAdd, for ARM, selects SNaNs first. So we have to preserve SNaN long enough for the correct NaN to be selected. Thus float16_to_float32_by_bits.

target-arm: A64: add stubs for a64 specific helpers We will need helpers that only make sense with AArch64.
