Samuel Tardieu	657ee48bec	Ignore instructions following a break from block in never_loop lint ... It is not sufficient to ignore break from a block inside the loop. Instructions after the break must be ignored, as they are unreachable. This is also true for all instructions in outer blocks and loops until the right block is reached.	2023-02-14 09:55:44 +01:00
Samuel Tardieu	e9dffa3910	Fix a bug in never_loop when anonymous blocks are nested in named blocks ... The following code ``` loop { 'a: { { } break 'a; } } ``` was detected as a never-looping loop.	2023-02-14 09:23:04 +01:00
Kartavya Vashishtha	9f3b6e9acd	don't emit AlwaysBreaks if it targets a block ... Introduced an ignored_ids parameter. Takes O(n^2) time in the worst case. Can be changed to collect block ids in first phase, and then filter with binary search in second.	2022-11-16 11:01:07 +05:30
Kartavya Vashishtha	989986144c	fix never_loop false positive ... on unconditional break to internal labeled block ref #9831	2022-11-12 20:36:30 +05:30
