Aaron Patterson ebaf56c013 YJIT: Implement getblockparam ... This implements the getblockparam instruction. There are two cases we need to handle depending on whether or not VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM is set in the environment flag. When the modified flag is unset, we need to call rb_vm_bh_to_procval to get a proc from our passed block, save the proc in the environment, and set the modified flag. In the case that the modified flag is set we are able to just use the existing proc in the environment. One quirk of this is that we need to call jit_prepare_routine_call early and ensure we update PC and SP regardless of the branch taken, so that we have a consistent SP offset at the start of the next instruction. We considered using a chain guard to generate these two paths separately, but decided against it because it's very common to see both and the modified case is basically a subset of the instructions in the unmodified case. This includes tests for both getblockparam and getblockparamproxy which was previously missing a test.		2022-05-12 14:34:18 -07:00
