The current default of 10 minutes is much longer than most tests need on
common hardware. The slow tests all now have a dg-timeout-factor
directive that gives them more time to run relative to the default. The
default can also be overridden in ~/.dejagnurc or DEJAGNU=site.exp, so
it seems unnecessary to have such a large default.
This reduces the default from 10 minutes to 6 minutes, which still seems
more than enough.

Options: -fopenmp and -fopenacc imply concurrent calls to a

Run-time recursion check: Always reset the check variable at the
end of the procedure; this avoids a bogus error with -fopenmp
when called twice nonconcurrently/nonrecursively. (Issue requires
using -fno-automatic or -fmax-stack-var-size= to trigger.)

This recently submitted test was found to fail on some Cortex-M
targets. This was because codegen on these CPUs would emit a ldr
instead of a movw/movt pair, resulting in an overall smaller test
(i.e. the branch wasn't as far) and the behaviour being tested
for not being triggered.
This commit doubles the size of the test to account for this.

As discussed in the PR, e.g. on x86_64 (both -m32 and -m64) there is no
double-word modulo and so we expand it to a __{,u}mod[dt]i3 call.
For certain constant divisors we can do better. E.g. consider
32-bit word-size, 0x100000000ULL % 3 == 1, so we can use partly the Hacker's
delight modulo by summing digits approach and optimize
unsigned long long foo (unsigned long long x) { return x % 3; }
as
unsigned long long foo (unsigned long long x) {
unsigned int sum, carry;
carry = __builtin_add_overflow ((unsigned int) x, (unsigned int) (x >> 32), &sum);
sum += carry;
return sum % 3;
}
Similarly, 0x10000000ULL % 5 == 1 (note, 1 << 28), so
unsigned long long bar (unsigned long long x) { return x % 5; }
as
unsigned long long bar (unsigned long long x) {
unsigned int sum = x & ((1 << 28) - 1);
sum += (x >> 28) & ((1 << 28) - 1);
sum += (x >> 56);
return sum % 5;
}
etc.
And we can do also signed modulo,
long long baz (long long x) { return x % 5; }
as
long long baz (long long x) {
unsigned int sum = x & ((1 << 28) - 1);
sum += ((unsigned long long) x >> 28) & ((1 << 28) - 1);
sum += ((unsigned long long) x >> 56);
/* Sum adjustment for negative x. */
sum += (x >> 63) & 3;
unsigned int rem = sum % 5;
/* And finally adjust it to the right interval for negative values. */
return (int) (rem + ((x >> 63) & -4));
}

- Define MULTILIB_DEFAULTS can reduce the total number of multilib if
the default arch and ABI are listed in the multilib config.
- This also simplify the implementation of --with-multilib-list.
gcc/ChangeLog:

* config/riscv/withmultilib.h: Remove.
This issue is found when we try to always define MULTILIB_DEFAULTS for -march
and -mabi for RISC-V back-end, however `-print-multi-lib` will skip
multi-lib setting if match any one of flag in MULTILIB_DEFAULTS, even
some options are specified in the option list with '!'.
e.g.
We have default march=rv32i and mabi=ilp32.
And we have following multi-lib set:
". !march=rv32i !march=rv32im !march=rv32imafc !mabi=ilp32 !mabi=ilp32f;"
"rv32i/ilp32 march=rv32i !march=rv32im !march=rv32imafc mabi=ilp32 !mabi=ilp32f;"
"rv32im/ilp32 !march=rv32i march=rv32im !march=rv32imafc mabi=ilp32 !mabi=ilp32f;"
"rv32imafc/ilp32f !march=rv32i !march=rv32ic !march=rv32im march=rv32imafc !mabi=ilp32 mabi=ilp32f;"
`-print-multi-lib` willl show `.` and `rv32imafc/ilp32f` only, because
the mabi=ilp32 is matched, however there is `!march=rv32i` in `rv32im/ilp32`, so
`rv32im/ilp32` should keep, because it reject march=rv32i.
Note: This can be reproduced via following configure options with patch [1]:
gcc/configure --target=riscv64-elf --with-arch=rv32i --with-abi=ilp32 \
--with-multilib-generator="rv32i-ilp32--;rv32im-ilp32--;rv32imafc-ilp32f--"
