Author: mstorsjo Date: Mon May 6 14:19:07 2019 New Revision: 360082 URL: http://llvm.org/viewvc/llvm-project?rev=360082&view=rev Log: [AArch64] Add __builtin_sponentry, for calling setjmp in MinGW
In MinGW, setjmp isn't expanded as a builtin in the compiler (like it is for MSVC), but manually hooked up as calls to the right underlying functions in headers. Using the actual CRT's real setjmp/longjmp functions requires this intrinsic. (Currently this is worked around by using MinGW specific reimplementations of setjmp/longjmp on aarch64.)
