6 years ago[Patch AArch64] Turn on frame pointer / partial fix for PR84521
Ramana Radhakrishnan [Mon, 26 Feb 2018 09:25:21 +0000 (09:25 +0000)]
[Patch AArch64] Turn on frame pointer / partial fix for PR84521

This fixes a GCC-8 regression that we accidentally switched off frame
pointers in the AArch64 backend when changing the defaults in the common
parts of the code. This breaks an ABI decision that was made in GCC at
the dawn of the port with respect to having a frame pointer at all
times.  If we really want to turn this off lets have a discussion around
that separately.

For now turn this back on and I believe this will leave PR84521 latent
again with -fomit-frame-pointer and (hopefully) make the ruby issue go
away. I'm asking Sudi to pick that up.

Bootstrapped and regression tested on AArch64-none-linux-gnu but I see
one regression in gcc.c-torture/execute/960419-2.c which needs to be
looked at next (PR84528, thanks Kyrill).

Ok to put in and then look at PR84528 ?

Character length cleanup for Coarray Fortran library

Following the change to use size_t for Fortran character lengths (PR

single-image implementation that is included in libgfortran is
updated, but this needs corresponding work in the OpenCoarray library
as well for multi-image support. I also fixed the types for the STOP
and ERROR STOP implementation in libgfortran, as the calling of them
is somewhat intertwined with the calling of the corresponding CAF
functions. I'll send the OpenCoarray changes as a separate pull
request to the OpenCoarrays repository.
