2020-08-20Fortran : rejected f0.d edit descriptor PR96436Mark Eggleston1-1/+9

2020-07-24PR 93567, G edit descriptor uses E instead of F editing in rounding mode UP.Dominique d'Humieres1-4/+8
The switch between FMT_E and FMT_F is based on the absolute value. Set r=0 for rounding toward zero and r = 1 otherwise.

2018-11-22Replace sync builtins with atomic builtinsJanne Blomqvist1-6/+18
The old __sync builtins have been deprecated for a long time now in favor of the __atomic builtins following the C++11/C11 memory model. This patch converts libgfortran to use the modern __atomic builtins. At the same time I weakened the consistency to relaxed for incrementing and decrementing the counter, and acquire-release when decrementing to check whether the counter is 0 and the unit can be freed. This is similar to e.g. std::shared_ptr in C++.

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
