Sebastien Bourdeauducq	bc0f82cad8	Revert "nac3artiq/codegen: fixed smax problem" ... We have LLVM 12 now and can use the intrinsic. This reverts commit 98d9f73afb.	2021-11-02 14:00:28 +08:00
pca006132	98d9f73afb	nac3artiq/codegen: fixed smax problem ... It turns out the smax intrinsic I use is a new one that is not supported in LLVM11. Now implemented with signed integer compare and select.	2021-11-02 11:10:21 +08:00
pca006132	84c5201243	with parallel/sequential support ... Behavior of parallel and sequential: Each function call (indirectly, can be inside a sequential block) within a parallel block will update the end variable to the maximum now_mu in the block. Each function call directly inside a parallel block will reset the timeline after execution. A parallel block within a sequential block (or not within any block) will set the timeline to the max now_mu within the block (and the outer max now_mu will also be updated). Implementation: We track the start and end separately. - If there is a start variable, it indicates that we are directly inside a parallel block and we have to reset the timeline after every function call. - If there is a end variable, it indicates that we are (indirectly) inside a parallel block, and we should update the max end value. Note: requires testing, it is difficult to inspect the output IR	2021-10-31 17:16:21 +08:00
