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.

target-arm: Implement WFE as a yield operation Implement WFE to yield our timeslice to the next CPU. 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: Recalculate hflags correctly after writes to CONTROL A write to the CONTROL register can change our current EL (by writing to the nPRIV bit). That means that we can't assume that s->current_el is still valid in trans_MSR_v7m() when we try to rebuild the hflags. Add a new helper rebuild_hflags_m32_newel() which, like the existing rebuild_hflags_a32_newel(), recalculates the current EL from scratch, and use it in trans_MSR_v7m(). This fixes an assertion about an hflags mismatch when the guest changes privilege by writing to CONTROL.

However if we use a cached current_el from before the change we'll rebuild the flags incorrectly. To fix this we introduce the ARM_CP_NEWEL CP flag to indicate the new EL should be used when recomputing the flags.

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.

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: 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: Vectorize USHL and SSHL These instructions shift left or right depending on the sign of the input, and 7 bits are significant to the shift. This requires several masks and selects in addition to the actual shifts to form the complete answer. That said, the operation is still a small improvement even for two 64-bit elements -- 13 vector operations instead of 2 * 7 integer operations.
