Using the original glibc headers under bits/ let's make small
modifications to use 64-bit time_t and off_t for both RV32 and RV64.
For the typesizes.h, here are justifications for the changes from the
generic version (based on Arnd's very helpful feedback):
- All the !__USE_FILE_OFFSET64 types (__off_t, __ino_t, __rlim_t, ...)
are changed to match the 64-bit replacements.
- __time_t is defined to 64 bit, but no __time64_t is added. This makes
sense as we don't have the time64 support for other 32-bit
architectures yet, and it will be easy to change when that happens.
- __suseconds_t is 64-bit. This matches what we use the kernel ABI for
the few drivers that are relying on 'struct timeval' input arguments
in ioctl, as well as the adjtimex system call. It means that timeval
has to be defined without the padding, unlike timespec, which needs
padding.

Remove a duplicate inclusion of <sysdeps/unix/sysdep.h> which is already
pulled via <sysdeps/unix/sysv/linux/generic/sysdep.h>, and the inclusion
of <errno.h> whose definition of `__set_errno' is not needed here.

sysdep.h redefines only the syscall where the generic implementation
still does not have actual 64-bit time_t support:
/* Workarounds for generic code needing to handle 64-bit time_t. */
/* Fix sysdeps/unix/sysv/linux/clock_getcpuclockid.c. */
#define __NR_clock_getres __NR_clock_getres_time64
/* Fix sysdeps/nptl/lowlevellock-futex.h. */
#define __NR_futex __NR_futex_time64
[...]
This patch also adds a comment that it is a workaround to handle 64-bit
time_t and on each #define comment for which implementation it intends
to.

With RV32 support the list of possible RISC-V system directories
increases to:
- /lib64/lp64d
- /lib64/lp64
- /lib32/ilp32d
- /lib32/ilp32
- /lib (only ld.so)
This patch changes the add_system_dir () macro to support the new ilp32d
and ilp32 directories for RV32. While refactoring this code let's split
out the confusing if statements into a loop to make it easier to
understand and extend.

Add a libm-test-ulps for RV32, this is the same as the RV64 one.
This dosn't match what is generated by running `make regen-ulps` on RV32
QEMU, but the current in tree RV64 doesn't match that either.

Conversions from a float to a long long on 32-bit RISC-V (RV32) may not
raise the correct exceptions on overflow, it also may raise spurious
"inexact" exceptions on non overflow cases. This patch fixes the
problem, similarly to the fix for MIPS, ARM and S390.

Specify the minimum kernel version for RISC-V 32-bit as the 5.4 kernel.
We require this commit: "waitid: Add support for waiting for the current
process group" for the kernel as it adds support for the P_PGID id for
the waitid syscall. Without this patch we can't replace the wait4
syscall on 64-bit time_t only systems.

This patch lays out the top-level organisation of the RISC-V 32-bit port.
It provides all the Implies files as well as various other fragments of
the build infrastructure.

Hi Alistair,
Oops, I reviewed the change heading, but did miss a typo:
s/infastructure/infrastructure/
Sorry about it.

I can see you did fix it here already though, thanks!
This is my final nit across the series, so I think there is no need to
repost for the sake of this trivial update unless someone else has any
concerns.

There is already RISC-V 64-bit port information in the documentation.
Let's add some documentation entries for the RISC-V 32-bit as well.

I just finished running the tests and the RV64 failing tests look like this:
FAIL: elf/tst-audit2
FAIL: nptl/tst-cancel28
FAIL: stdlib/tst-strfrom
FAIL: stdlib/tst-strfrom-locale
NOTE: This doesn't include the failing maths tests (that is an issue
only when running on QEMU) or the PLT issue for RISC-V 32-bit.

Sigh, I hoped the results would be the same, which we could then blame on
some common issues across RISC-V ports. I can imagine `tst-lockf' being
caused by some Linux kernel issue, however `dlvsym' issues likely come
from our dynamic loader or maybe the static linker.
Would you be able to see if there is any interesting information in the
respective .out files and/or the overall test log?
NB to save some processing time and have results available sooner you can
rerun coarse subsets of the test suite if you need to, by removing the
relevant (or all) .out files from any previous testing and then running:
$ make <args> subdirs="<foo> <bar> ..." check
to limit testing to the subdirectories named, e.g.:
$ make <args> subdirs="elf io" check
(substitute <args> with any other arguments you usually use with testing
glibc).

Ack. Can you check if the PLT issue has been fixed with
<https://sourceware.org/pipermail/binutils/2020-August/112750.html>?

You can also make $subdir/tests to run tests in a single subdir.

Yep, see below for the RV32 failure logs:

I'm assuming that stdlib/tst-strfrom and stdlib/tst-strfrom-locale are
just related to QEMU FP bugs, as they fail for both RV32 and RV64.
I'll look into the missing _sys_errlist symbol

Yes, using the latest binutils with those patches applied seems to fix
the PLT failures.

Well, we have this in NEWS:
* The deprecated symbols sys_errlist, _sys_errlist, sys_nerr, and _sys_nerr
are no longer available to newly linked binaries, and their declarations
have been removed from from <stdio.h>. They are exported solely as
compatibility symbols to support old binaries. All programs should use
strerror or strerror_r instead.
so it looks like a test case bug to me; the symbol is expected not to be
there given that we have no compatibility with previous library versions
to take care of. Not a showstopper for RV32 inclusion IMO.

This might be more interesting to look into further; as `len' is of the
`off_t' type it would be good to double-check it is correctly handled.

Agreed, and in any case RV32 does not perform any worse than RV64. Of
course it would be good to look into it anyway, but it shouldn't be a
showstopper for RV32 inclusion IMO.

Good to know, thanks for confirming. So I guess we can ignore the PLT
check failure and expect anyone caring about clean results to use most up
to date binutils once the fix has been included (and until then use the
patch applied locally).
I've cc-ed Nelson to give him some incentive to upstream his fix quickly.

Yep, it looks like this is a test failure. I'll send a patch out now with a fix.

I have fixed this as well, the test is incorrectly calling the lockf()
function (not 64-bit version). I'll send a patch.
With these three fixed we now have the same two failures as RV64 :)

Shouldn't `lockf' and `lockf64' be aliases to each other on RV32? IOW do
we support a non-LFS environment at all?
(Of course the test case may still require an adjustment as it seems to
imply non-LFS support to be present, i.e.:
/* Check if non-LFS interface cap access to 32-bif off_t. */
TEST_COMPARE (lseek64 (temp_fd, (off64_t)INT32_MAX, SEEK_SET),
(off64_t)INT32_MAX);
though I find it odd as 64-bit targets starting from DEC Alpha have never
had it.)

Good to know that the patch could help. Thanks for the information,
Maciej and Alistair. I will resend at least the PLT improvement patch
(Regard the R_RISCV_CALL and R_RISCV_CALL_PLT as the same one) ASAP.

Thanks for that.
Just an update on test cases.
With the binutils patch applied I see no failures when running
./scripts/build-many-glibcs.py on my x86 machine (without the binutils
patch I see PLT failures).
With the binutils patch applied and the two patches I just sent to the
list I see these failures on RV32 in QEMU:
FAIL: nptl/tst-cancelx16
FAIL: stdlib/tst-strfrom
FAIL: stdlib/tst-strfrom-locale
nptl/tst-cancelx16.out fails with:
cleanup handler not called
I think the other two failures are related to:
https://sourceware.org/legacy-ml/libc-alpha/2018-01/msg01062.html
I'm planning on pushing this series tomorrow.

Umm, in the future please run `git rebase --ignore-date origin/master'
before pushing changes upstream to a GNU toolchain repository so that
change dates remain chronological in the branch.

Will this be backported to binutils 2.35 branch (which is what
build-many-glibcs.py uses by default - thus, showing test failures
https://sourceware.org/pipermail/libc-testresults/2020q3/006687.html on
the bot with GCC 10)?

The tests of _sys_errlist and _sys_siglist in elf/tst-libc_dlvsym.h need
TEST_COMPAT (libc, GLIBC_2_0, GLIBC_2_32) conditionals added, to disable
them for configurations lacking those symbols.

I think my previous comments still apply on how you might need a hook in
these functions to handle the RISC-V rules about NaN results for
floating-point operations.

Thanks! This fixes the test failure. I'm just running some tests then
I'll send a patch.

For anyone interested I'm talking about the 32-bit RISC-V port at
Plumbers next week. Please come along and discuss

This series has now been fully reviewed :)
I am planning on pushing it next week unless anyone has any comments
