Add ms_abi and sysv_abi attribute handling. Based on a patch by Benno Rice! llvm-svn: 189644

Support __builtin_ms_va_list. Summary: This change adds support for `__builtin_ms_va_list`, a GCC extension for variadic `ms_abi` functions. The existing `__builtin_va_list` support is inadequate for this because `va_list` is defined differently in the Win64 ABI vs. the System V/AMD64 ABI. Depends on D1622.

[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 `{{.*}} `.

Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940

[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 `{{.*}} `.

Support __builtin_ms_va_list. Summary: This change adds support for `__builtin_ms_va_list`, a GCC extension for variadic `ms_abi` functions. The existing `__builtin_va_list` support is inadequate for this because `va_list` is defined differently in the Win64 ABI vs. the System V/AMD64 ABI. Depends on D1622.

Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940

[clang] Apply MS ABI details on __builtin_ms_va_list on non-windows platforms on x86_64 This fixes inconsistencies in the ms_abi.c testcase. Also add a couple cases of missing double pointers in the windows part of the testcase; the outcome of building that testcase on windows hasn't changed, but the previous form of the test was imprecise (checking for "%[[STRUCT_FOO]]*" when clang actually generates "%[[STRUCT_FOO]]**"), which still used to match. Ideally this would share code with the native Windows case, but X86_64ABIInfo and WinX86_64ABIInfo aren't superclasses/subclasses of each other so it's impractical, and the code to share currently only consists of a couple lines.

Fix for #31362 - ms_abi is implemented incorrectly for values >=16 bytes. Summary: This patch is a fix for following issue: https://bugs.llvm.org/show_bug.cgi?id=31362 The problem was caused by front end lowering C calling conventions without taking into account calling conventions enforced by attribute. In this case win64cc was no correctly lowered on targets other than Windows.

Reapply "OpaquePtr: Add type to sret attribute" This reverts commit eb9f7c28e5fe6d75fed3587023e17f2997c8024b. Previously this was incorrectly handling linking of the contained type, so this merges the fixes from D88973.

// WIN64: define dso_local void @f7(%struct.i128* noalias sret(%struct.i128) align 8 %agg.result, %struct.i128* %a)
[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 `{{.*}} `.
