Fangrui Song	fd739804e0	[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences ... For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.	2020-12-31 00:27:11 -08:00
Matt Arsenault	0a7cd99a70	Reapply "OpaquePtr: Add type to sret attribute" ... This reverts commit eb9f7c28e5. Previously this was incorrectly handling linking of the contained type, so this merges the fixes from D88973.	2020-10-16 11:05:02 -04:00
Tres Popp	eb9f7c28e5	Revert "OpaquePtr: Add type to sret attribute" ... This reverts commit 55c4ff91bd. Issues were introduced as discussed in https://reviews.llvm.org/D88241 where this change made previous bugs in the linker and BitCodeWriter visible.	2020-09-29 10:31:04 +02:00
Matt Arsenault	55c4ff91bd	OpaquePtr: Add type to sret attribute ... Make the corresponding change that was made for byval in b7141207a4. Like byval, this requires a bulk update of the test IR tests to include the type before this can be mandatory.	2020-09-25 14:07:30 -04:00
Qiu Chaofan	ef30a00a57	[NFC] Add float aggregate ABI test for PowerPC ... 4c5a93bd landed adjustment to handle C++20 no_unique_address attribute correctly, clang treats empty members in aggregate type differently if having this attribute. This commit adds necessary test for PowerPC target to reflect this change.	2020-07-16 00:11:09 +08:00
