Irit Katriel added the comment: The way these two opcodes are combined by the compiler to implement except* is described in the pseudo code here: https://github.com/python/cpython/pull/29581#issuecomment-975660029 except* uses JUMP_IF_NOT_EG_MATCH. The excepts (not-*) that collect

Irit Katriel added the comment: The second opcode that the PR adds is PREP_RERAISE_STAR. This opcode takes a list that contains: 1. all the exceptions that were raised in the executed except* clauses 2. the unmatched part of the exception group It constructs the exception group that needs to

Irit Katriel added the comment: The PR adds two new opcodes. Let's start with the simpler of the two - JUMP_IF_NOT_EG_MATCH. This is the exception-group variation on JUMP_IF_NOT_EXC_MATCH. JUMP_IF_NOT_EXC_MATCH checks for a match by checking if the exception is of the given type. The

Mark Shannon added the comment: PR 29581 resulted in a 1% slowdown, which is not terrible, but code not using except* should not be slowed down at all. IMO, the way to avoid the slowdown is to implement except* using the existing instruction set (perhaps with a few minor additions) We

Guido van Rossum added the comment: We should have a discussion here about improvements that Mark Shannon would like to see, in particular to do more work in the compiler instead of the interpreter. -- nosy: +Mark.Shannon, gvanrossum ___ Python
