RISC-V -menable-experimental-extensions option

2020-12-07 Thread Jim Wilson
I'm not aware of any other target that has a similar feature, so I thought a bit of discussion first might be useful. For most ISAs, there is one organization that owns it, and does development internally, in private. For RISC-V, the ISA is owned by RISC-V International which has no developers.

[PATCH 0/2] Support libc with stdio-only I/O in libstdc++

2020-12-07 Thread Keith Packard via Gcc
The current libstdc++ basic_file_stdio.cc code assumes a POSIX API underneath the stdio implementation provided by the host libc. This means that the host must provide a fairly broad POSIX file API, including read, write, open, close, lseek and ioctl. This patch changes basic_file_stdio.cc to only
