5d100fd2c6 cpuNbitalu is not the correct type for fpc_atomic_cmp_xchg_alu on webassembly 2025-01-08 12:06:52 +01:00

6035058a21 Shorten generic atomic implementations to offset the LoC cost of the commit before last. 
This also fixes wrong fpc_atomic_sub_8 and fpc_atomic_sub_16 emulations.

ae938e16a5 * correctly disable the Atomic*Lock functions for the fpc_atomic_cmp_xchg_*() helper fallback of the CPU size 2024-12-16 23:13:36 +01:00

e94d02a067 * with all existing RTLs switched over to the atomic intrinsics, the define FPC_SYSTEM_INTERLOCKED_USE_INTRIN can be removed again 2024-12-12 22:05:20 +01:00
Sven/Sarah Barth
9cbc802d0d + add platform independent helper routines for the atomic intrinsics; these only require the implementation of the size specific fpc_atomic_cmp_xhg_* helper, but if only the CPU size specific helper is implemented the others will at least be safe for multi threading inside the same process 2024-12-12 22:05:14 +01:00

799c22d553 Revert " * patch by Rika: SwapEndian([u]int16) has unnecessary “and $FFFF”, resolves #39814" 
This reverts commit f92102a5f2.

The and $ffff is needed to avoid range check warnings when the function is inlined with a constant parameter
