Subject: Passing big structs by value fails on hppa-linux
Date: Sun, 26 Sep 2021 18:16:03 -0400 [thread overview]
Message-ID: <0b66161e-56e7-b358-672d-88c9b7661060@bell.net> (raw)
This change
commit 43e4ad4d7b4bcc87ee447736a1172b2801a47908 (HEAD, refs/bisect/bad)

Test passing structs by value
exposed a problem on the hppa linux port:
Running ../../libffi/testsuite/libffi.call/call.exp ...
FAIL: libffi.call/struct_by_value_big.c -W -Wall -Wno-psabi -O0 execution test
FAIL: libffi.call/struct_by_value_big.c -W -Wall -Wno-psabi -O2 execution test
Currently, the code assumes that structs larger than 8 bytes are passed by hidden reference.
Probably, this has broken builds of python_cffi, etc.
