2023-12-11libgfortran: Replace mutex with rwlockLipeng Zhu1-8/+8
This patch try to introduce the rwlock and split the read/write to unit_root tree and unit_cache with rwlock instead of the mutex to increase CPU efficiency. In the get_gfc_unit function, the percentage to step into the insert_unit function is around 30%, in most instances, we can get the unit in the phase of reading the unit_cache or unit_root tree. So split the read/write phase by rwlock would be an approach to make it more parallel. BTW, the IPC metrics can gain around 9x in our test server with 220 cores.

2018-09-14[libgfortran] Fix uninitialized variable use in fallback_accessKyrylo Tkachov1-6/+14
I've been tracking down a bug in a Fortran program on a newlib target and it boils down to fallback_access doing something bad. The unconditional calls to close cause havoc when open doesn't get called due to the short-circuiting in the if-statement above because the fd is uninitialised. In my environment GCC ends up calling close on file descriptor 0, thus trying to close stdin. This patch tightens up the calling so that close is called only when the corresponding open call succeeded. With this my runtime failure disappears. Bootstrapped and tested on aarch64-none-linux-gnu. Though that doesn't exercise this call I hope it's an obviously correct change. * io/unix.c (fallback_access): Avoid calling close on uninitialized file descriptor. From-SVN: r264305

2018-01-02PR libgfortran/83649 Chunk large reads and writesJanne Blomqvist1-8/+42
It turns out that Linux never reads or writes more than 2147479552 bytes in a single syscall. For writes this is not a problem as libgfortran already contains a loop around write() to handle short writes. But for reads we cannot do this, since then read will hang if we have a short read when reading from the terminal. Also, there are reports that macOS fails I/O's larger than 2 GB. Thus, to work around these issues do large reads/writes in chunks. The testcase from the PR program largewr integer(kind=1) :: a(2_8**31+1) a = 0 a(size(a, kind=8)) = 1 open(10, file="largewr.dat", access="stream", form="unformatted") write (10) a close(10) a(size(a, kind=8)) = 2 open(10, file="largewr.dat", access="stream", form="unformatted") read (10) a if (a(size(a, kind=8)) == 1) then print *, "All is well" else print *, "Oh no" end if end program largewr fails on trunk but works with the patch.

2016-10-09PR 67585 Handle EINTRJanne Blomqvist1-26/+60
Many POSIX systems have the bad habit of not restarting interrupted syscalls. On these systems it's up to the user to check for an error with errno == EINTR and restart manually.
