Hi!
As discussed earlier, all other -static-lib* options are Driver only,
these 2 are Driver in common.opt and Fortran in lang.opt.
The spec files never pass the -static-lib* options down to any compiler
(f951 etc.), so the 2 errors below are reported only when one
runs ./f951 -static-libgfortran

The function jump instruction in normal mode is 'bl',
so the scope of the function jump is +-128MB.
Now we've added support for 'medium' mode, this mode is
to complete the function jump through two instructions:
pcalau12i + jirl
So in this mode the function jump range is increased to +-2GB
Hi, Lulu,
I think there is a typo in your subject line.

Hi Ian,
Thanks for your input!
I am not familiar with Go runtime internals at all, but the patch below
at least compiles for me. Let me know if this works for you too / if
there is a better way to do this. The untyped uintptr_t seems to be
necessary as otherwise I encountered errors about &sevp e

The default expansion for bswap16 is two extractions (shift/and)
followed by an insertation (ior) and then a zero extend. This can be improved
with ZBB enabled to just full byteswap followed by a (logical) shift right.
This patch adds a new pattern for this which does that.

Just some improvements for bswap and ZBB including a testsuite change that will
allow more testing to happen.
Thanks,

The problem here is the bswap2 pattern had a check for TARGET_64BIT
but then used the X iterator. Since the X iterator is either SI or DI depending
on the setting TARGET_64BIT, there is no reason for the TARGET_64BIT.
OK? Built and tested on both riscv32-linux-gnu and riscv64

While looking for testcases to quickly test, I Noticed that
check_effective_target_bswap was not enabled for riscv when
ZBB is enabled. This patch checks if ZBB is enabled when
targeting RISCV* for bswap.
OK? Ran the testsuite for riscv32-linux-gnu both with and without ZBB e
Dear all,
the simplification of the TRANSFER intrinsic produces a
redundant representation of the result, one in expr->value
and another in expr->representation.string. This is done
to ensure a safe "round-trip" for nested TRANSFER.
In a subsequent use of this result we either need to make
sure

Hi, it seems that this warning still report if I revert my patch. Am I right?
Feel free to correct me. Maybe I need to try it again?

The warning will not be still there. The reason is NUM_POLY_INT_COEFFS
defaults to 1 which means vf.is_constant (&

The fix is not in the RISC-V port, the fix needs to happen in
vect_gen_vector_loop_niters (tree-vect-loop-manip.cc).
I described why the code is broken, the second use of const_vf is
