  "message": "[CodeGen] Fix lpad padding at section start after empty block (#112595)\n\nIf a landing pad is at the very start of a split section, it has to be\npadded by a nop instruction. Otherwise its offset is marked as zero in\nthe LSDA, which means no landing pad (leading it to be skipped).\n\nLLVM already handles this. If a landing pad is the first machine block\nin a section, a nop is inserted to ensure a non-zero offset. However, if\nthe landing pad is preceeded by an empty block, the nop would be\nomitted.\n\nTo fix this, this patch adds a field to machine blocks indicating\nwhether this block contains the first instruction in its section. This\nvariable is then used to determine whether to emit the padding.\n\nCo-authored-by: Jinjie Huang \u003chuangjinjie@bytedance.com\u003e",
