Hi Jakub,
This patch fixes the two ICEs listed on PR77371.
One is due to the Fortran omp_privatize_by_reference hook returning true
for types like 'character(kind=1)[1:XX] *', causing them to be processed
by the path intended for C++ reference types.
The other one is simply not setting 'remove = t

Hi Jakub,
this patch set is a port of the OpenACC tile clause functionality from the gomp4
branch. The tile clause allows the programmer to specify the tiling of an
OpenACC loop nest.
These patches were mostly implemented by Nathan, with the Fortran
front-end bits by Cesar. I'm just upstreaming th

This part is the bulk of the patch set. It consists of

of this in omp-low, as well as loop auto-partitioning adjustments
that help improve generated code.
This patch corresponds to the gomp4 committed patches:

This patch adjusts the initialization of __sync built-in functions:
instead of conditionalizing on TARGET_LINUX_ABI, directly place the
target-hook #define in config/nios2/linux.h. This appears to be in line

Hi,
we've been encountering an ICE for OpenACC host_data sections, which
has a use_device() clause similar to OpenMP use_device_ptr.
The ICE happens in make_decl_rtl() for scan-created variables, which IIUC,

ression from the PR32219 discussion, that the solution

Hi Savin,
I've committed your patch for PR59784; the fix seems small enough to
accept directly. Thanks a lot for catching this.

SFmode to DFmode ca
This patch adds large GOT support for the Nios II backend. Tested by
running glibc tests with -fPIC forced on. A few smaller libgcc fixes
are also included as well. Patch committed.

For the default multilib settings, it looks like you just intended to
use -mcustom-fpu-cfg=60-2. I suggest you modify t-rtems to do that
instead of enumerating the individual FPU insn options.
Other than that, the patch looks okay.

, plus nios2 GDB's prologue analyzer is capable
of determining where FP is stored. Still this needs to fixed to be
conformant to the ABI.
Tested (both the compiler and gdb) and applied to trunk.

Bootstrapped and tested on i686 and x86_64 without regressions. Is this
okay for trunk?
