Slava Zakharin	1563a8752b	[flang][runtime] Allow building CUDA PTX library without global vars definitions. (#90280)	2024-04-29 08:19:45 -07:00
Slava Zakharin	8ebf741136	[flang][runtime] Prepare enabling PRINT of integer32 for device. (#86247) ... This commit adds required files into the offload build closure, which means adding RT_API_ATTRS and other markers. The implementation does not work for CUDA yet, because of std::variant,swap,reverse usage. These issues will be resolved separately (e.g. by using libcudacxx header files).	2024-03-25 16:01:25 -07:00
Slava Zakharin	71e0261fb0	[flang][runtime] Added Fortran::common::optional for use on device. ... This is a simplified implementation of std::optional that can be used in the offload builds for the device code. The methods are properly marked with RT_API_ATTRS so that the device compilation succedes.

Peter Klausler	bafbae238a	[flang] Initial UTF-8 support in runtime I/O ... Implements UTF-8 encoding and decoding for external units with OPEN(ENCODING='UTF-8'). This encoding applies to default CHARACTER values that are not 7-bit ASCII as well as to the wide CHARACTER kinds 2 and 4. Basic testing is in place via direct calls to the runtime I/O APIs, but serious checkout awaits lowering support of the wide CHARACTER kinds.
