Date: Thu, 10 Jun 2021 16:52:43 +0300 [thread overview] Message-ID: <20210610135243.GA3944@tarantool.org> (raw) In-Reply-To: <c7b188e651fc921cac42576961e0617594b16dad.1621859367.git.skaplun@tarantool.org> Sergey, Thanks for the patch! There are still typos left after fixing Sergos review comments (the commit message is taken from the branch). Otherwise, LGTM. | ARM64: Fix xpcall() error case (really). | | Thanks to François Perrad and Stefan Pejic. | | (cherry picked from commit d417ded17945b4211608d497d50b509e0274f5e0) | | Premature decrement of VM's RC register before switch to fff_fallback | handler during processing `xpcall()` fast function leads to incorrect | stack layout (not enough arguments on stack), when `xpcall()` calls Typo: s/calls/is called/. | without a second argument or if it is not a function (see | <test/lua-Harness-tests/301-basic.t:832> Typo: looks like line underfull (in LaTeX terms). | test in lua-Harness test suite). While further error processing it leads | to incorrect error message, due to stack inconsistency. | | This patch stores intermediate result into TMP1 register (it does not | determine fallback's behaviour and there is no way to return from | fallback back to xpcall processing with spoiled TMP1) and moves RC | setting after the switch to the fallback handler. | | Sergey Kaplun: | * added the description for the problem | | Resolves tarantool/tarantool#6093 | Part of tarantool/tarantool#5629 -- Best regards, IM
