glibc 2.34 and later doesn't have separate libpthread (libpthread.so.0 is a
dummy shared library with just some symbol versions for compatibility, but
all the pthread_* APIs are in libc.so.6).
So, we don't need to do the .weakref dances to check whether a program
has been linked with -lpthread or not, in dynamically linked apps those
will be always true anyway.
In -static linking, this fixes various issues people had when only linking
some parts of libpthread.a and getting weird crashes. A hack for that was
what e.g. some Fedora glibcs used, where libpthread.a was a library
containing just one giant *.o file which had all the normal libpthread.a
*.o files linked with -r together.
libstdc++-v3 actually does something like this already since r10-10928,
the following patch is meant to fix it even for libgfortran, libobjc and
whatever else uses gthr.h.

The following testcase is miscompiled because the code to decrement
vn on negative value with all ones in most significant limb (even partial)
and 0 in most significant bit of the second most significant limb doesn't
take into account the case where all bits below the most significant limb
are zero. This has been a problem both in the version before yesterday's
commit where it has been done only if un was one shorter than vn before this
decrement, and is now problem even more often when it is done earlier.
When we decrement vn in such case and negate it, we end up with all 0s in
the v2 value, so have both the problems with UB on __builtin_clz* and the
expectations of the algorithm that the divisor has most significant bit set
after shifting, plus when the decremented vn is 1 it can SIGFPE on division
by zero even when it is not division by zero etc. Other values shouldn't
get 0 in the new most significant limb after negation, because the
bitint_reduce_prec canonicalization should reduce prec if the second most
significant limb is all ones and if that limb is all zeros, if at least
one limb below it is non-zero, carry in will make it non-zero.
The following patch fixes it by checking if at least one bit below the
most significant limb is non-zero, in that case it decrements, otherwise
it will do nothing (but e.g. for the un < vn case that also means the
divisor is large enough that the result should be q 0 r u).

The following testcase aborts on aarch64-linux but does not on x86_64-linux.
In both cases there is UB in the __divmodbitint4 implemenetation.
When the divisor is negative with most significant limb (even when partial)
all ones, has at least 2 limbs and the second most significant limb has the
most significant bit clear, when this number is negated, it will have 0
in the most significant limb.
Already in the PR114397 r14-9592 fix I was dealing with such divisors, but
thought the problem is only if because of that un < vn doesn't imply the
quotient is 0 and remainder u.
But as this testcase shows, the problem is with such divisors always.
What happens is that we use __builtin_clz* on the most significant limb,
and assume it will not be 0 because that is UB for the builtins.
Normally the most significant limb of the divisor shouldn't be 0, as
guaranteed by the bitint_reduce_prec e.g. for the positive numbers, unless
the divisor is just 0 (but for vn == 1 we have special cases).
The following patch moves the handling of this corner case a few lines
earlier before the un < vn check, because adjusting the vn later is harder.

This patch adds support in gcc+gcov for modified condition/decision
coverage (MC/DC) with the -fcondition-coverage flag. MC/DC is a type of
test/code coverage and it is particularly important for safety-critical
applicaitons in industries like aviation and automotive. Notably, MC/DC
is required or recommended by:
* DO-178C for the most critical software (Level A) in avionics.
* IEC 61508 for SIL 4.
* ISO 26262-6 for ASIL D.
From the SQLite webpage:
Two methods of measuring test coverage were described above:
"statement" and "branch" coverage. There are many other test
coverage metrics besides these two. Another popular metric is
"Modified Condition/Decision Coverage" or MC/DC. Wikipedia defines
MC/DC as follows:
* Each decision tries every possible outcome.
* Each condition in a decision takes on every possible outcome.
* Each entry and exit point is invoked.
* Each condition in a decision is shown to independently affect
the outcome of the decision.
In the C programming language where && and || are "short-circuit"
operators, MC/DC and branch coverage are very nearly the same thing.
The primary difference is in boolean vector tests. One can test for
any of several bits in bit-vector and still obtain 100% branch test
coverage even though the second element of MC/DC - the requirement
that each condition in a decision take on every possible outcome -
might not be satisfied.
https://sqlite.org/testing.html#mcdc
MC/DC comes in different flavors, the most important being unique cause
MC/DC and masking MC/DC. This patch implements masking MC/DC, which is
works well with short circuiting semantics, and according to John
Chilenski's "An Investigation of Three Forms of the Modified Condition
Decision Coverage (MCDC) Criterion" (2001) is as good as unique cause at
catching bugs.
Whalen, Heimdahl, and De Silva "Efficient Test Coverage Measurement for
MC/DC" describes an algorithm for finding the masking table from an AST
walk, but my algorithm figures this out by analyzing the control flow
graph. The CFG is considered a reduced ordered binary decision diagram
and an input vector a path through the BDD, which is recorded. Specific
edges will mask ("null out") the contribution from earlier path
segments, which can be determined by finding short circuit endpoints.
Masking is most easily understood as circuiting of terms in the
reverse-ordered Boolean function, and the masked conditions do not
affect the decision like short-circuited conditions do not affect the
decision.
A tag/discriminator mapping from gcond->uid is created during
gimplification and made available through the function struct. The
values are unimportant as long as basic conditions constructed from a
single Boolean expression are given the same identifier. This happens in
the breaking down of ANDIF/ORIF trees, so the coverage generally works
well for frontends that create such trees.
Like Whalen et al this implementation records coverage in fixed-size
bitsets which gcov knows how to interpret. Recording conditions only
requires a few bitwise operations per condition and is very fast, but
comes with a limit on the number of terms in a single boolean
expression; the number of bits in a gcov_unsigned_type (which is usually
typedef'd to uint64_t). For most practical purposes this is acceptable,
and by default a warning will be issued if gcc cannot instrument the
expression. This is a practical limitation in the implementation, and
not a limitation of the algorithm, so support for more conditions can be
supported by introducing arbitrary-sized bitsets.
In action it looks pretty similar to the branch coverage. The -g short
opt carries no significance, but was chosen because it was an available
option with the upper-case free too.
gcov --conditions:
3: 17:void fn (int a, int b, int c, int d) {
3: 18: if ((a && (b || c)) && d)
conditions covered 3/8
condition 0 not covered (true false)
condition 1 not covered (true)
condition 2 not covered (true)
condition 3 not covered (true)
1: 19: x = 1;
-: 20: else
2: 21: x = 2;
3: 22:}
gcov --conditions --json-format:
"conditions": [
{
"not_covered_false": [
0
],
"count": 8,
"covered": 3,
"not_covered_true": [
0,
1,
2,
3
]
}
],
Expressions with constants may be heavily rewritten before it reaches
the gimplification, so constructs like int x = a ? 0 : 1 becomes
_x = (_a == 0). From source you would expect coverage, but it gets
neither branch nor condition coverage. The same applies to expressions
like int x = 1 || a which are simply replaced by a constant.
The test suite contains a lot of small programs and functions. Some of
these were designed by hand to test for specific behaviours and graph
shapes, and some are previously-failed test cases in other programs
adapted into the test suite.

This is just part of the changes, mostly for non-gcc directories.

Original bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111731
The unwinding mechanism registers both the code range and the unwind
table itself within a b-tree lookup structure. That data structure
assumes that is consists of non-overlappping intervals. This
becomes a problem if the unwinding table is embedded within the
code itself, as now the intervals do overlap.
To fix this problem we now keep the unwind tables in a separate
b-tree, which prevents the overlap.

The Knuth's division algorithm relies on the number of dividend limbs
to be greater ore equal to number of divisor limbs, which is why
I've added a special case for un < vn at the start of __divmodbitint4.
Unfortunately, my assumption that it then implies abs(v) > abs(u) and
so quotient must be 0 and remainder same as dividend is incorrect.
This is because this check is done before negation of the operands.
While bitint_reduce_prec reduces precision from clearly useless limbs,
the problematic case is when the dividend is unsigned or non-negative
and divisor is negative. We can have limbs (from MS to LS):
dividend: 0 M ?...
divisor: -1 -N ?...
where M has most significant bit set and M >= N (if M == N then it
also the following limbs matter) and the most significant limbs can
be even partial. In this case, the quotient should be -1 rather than
0. bitint_reduce_prec will reduce the precision of the dividend so
that M is the most significant limb, but can't reduce precision of the
divisor to more than having the -1 as most significant limb, because
-N doesn't have the most significant bit set.
The following patch fixes it by detecting this problematic case in the
un < vn handling, and instead of assuming q is 0 and r is u will
decrease vn by 1 because it knows the later code will negate the divisor
and it can be then expressed after negation in one fewer limbs.

While for __mulbitint3 we actually don't negate anything and perform the
multiplication in unsigned style always, for __divmodbitint4 if the operands
aren't unsigned and are negative, we negate them first and then try to
negate them as needed at the end.
quotient is negated if just one of the operands was negated and the other
wasn't or vice versa, and remainder is negated if the first operand was
negated.
The case which doesn't work correctly is if due to limited range of the
operands we perform the division/modulo in some smaller number of limbs
and then extend it to the desired precision of the quotient and/or
remainder results. If they aren't negated, the extension is done with
memset to 0, if they are negated, the extension was done with memset
to -1. The problem is that if the quotient or remainder is zero,
then bitint_negate negates it again to zero (that is ok), but we should
then extend with memset to 0, not memset to -1.
The following patch achieves that by letting bitint_negate also check if
the negated operand is zero and changes the memset argument based on that.

As PR109987 and its duplicated bugs show, -mno-power8-vector
(and -mno-power9-vector) cause some problems and as Segher
pointed out in [1] they are workaround options, so this patch
is to remove -m{no,}-power{8,9}-options. Like what we did
for option -mdirect-move before, this patch still keep the
corresponding internal flags and they are automatically set
based on -mcpu. The test suite update takes some efforts,
it consists of some aspects:
- effective target powerpc_p{8,9}vector_ok are removed
and replaced with powerpc_vsx_ok.
- Some cases having -mpower{8,9}-vector are updated with
-mvsx, some of them already have -mdejagnu-cpu. For
those that don't have -mdejagnu-cpu, if -mdejagnu-cpu
is needed for the test point, then it's appended;
otherwise, add additional-options -mdejagnu-cpu=power{8,9}
if has_arch_pwr{8,9} isn't satisfied.
- Some test cases are updated with explicit -mvsx.
- Some test cases with those two option mixed are adjusted
to keep the test points, like -mpower8-vector
-mno-power9-vector are updated with -mdejagnu-cpu=power8
-mvsx etc.
- Some test cases with -mno-power{8,9}-vector are updated
by replacing -mno-power{8,9}-vector with -mno-vsx, or
just removing it.
- For some cases, we don't always specify -mdejagnu-cpu to
avoid to restrict the testing coverage, it would check
has_arch_pwr{8,9} and appended that as need.
- For vect test cases run, it doesn't specify -mcpu=power9
for power10 and up.
Bootstrapped and regtested on:
- powerpc64-linux-gnu P7/P8/P9 {-m32,-m64}
- powerpc64le-linux-gnu P8/P9/P10
Although it's stage4 now, as the discussion in PR113115 we
are still eager to neuter these two options, so is it ok

This allows the same trampoline pattern to be used on all linux variants
rather than restricting it to linux gnu.

Fix a typo in __gthr_win32_abs_to_rel_time that caused it to return a
relative time in seconds instead of milliseconds. As a consequence,
__gthr_win32_cond_timedwait called SleepConditionVariableCS with a
1000x shorter timeout; this caused ~1000x more spurious wakeups in
CV timed waits such as std::condition_variable::wait_for or wait_until,
resulting generally in much higher CPU usage.
This can be demonstrated by this sample program:
```
int main() {
std::condition_variable cv;
std::mutex mx;
bool pass = false;

On builds based on non-affected threading models (e.g. POSIX on Linux,
or winpthreads or MCF on Win32) the output is something like
```
pass: 0; wakeups: 2; elapsed: 2000 ms
pass: 1; wakeups: 2; elapsed: 991 ms
pass: 1; wakeups: 2; elapsed: 996 ms
```
while with the Win32 threading model we get
```
pass: 0; wakeups: 1418; elapsed: 2000 ms
pass: 1; wakeups: 479; elapsed: 988 ms
pass: 1; wakeups: 2; elapsed: 992 ms
```
(notice the huge number of wakeups in the timed wait cases only).
This commit fixes the conversion, adjusting the final division by
NSEC100_PER_SEC to use NSEC100_PER_MSEC instead (already defined in the
file and not used in any other place, so probably just a typo).

As I wrote earlier, I was seeing
FAIL: gcc.dg/torture/bitint-24.c -O0 execution test
FAIL: gcc.dg/torture/bitint-24.c -O2 execution test
with the ia32 _BitInt enablement patch on i686-linux. I thought
floatbitintxf.c was miscompiled with -O2 -march=i686 -mtune=generic, but it
turned out to be UB in it.
If a signed _BitInt to be converted to binary floating point has
(after sign extension from possible partial limb to full limb) one or
more most significant limbs equal to all ones and then in the limb below
(the most significant non-~(UBILtype)0 limb) has the most significant limb
cleared, like for 32-bit limbs
0x81582c05U, 0x0a8b01e4U, 0xc1b8b18fU, 0x2aac2a08U, -1U, -1U
then bitint_reduce_prec can't reduce it to that 0x2aac2a08U limb, so
msb is all ones and precision is negative (so it reduced precision from
161 to 192 bits down to 160 bits, in theory could go as low as 129 bits
but that wouldn't change anything on the following behavior).
But still iprec is negative, -160 here.
For that case (i.e. where we are dealing with an negative input), the
code was using 65 - __builtin_clzll (~msb) to compute how many relevant
bits we have from the msb. Unfortunately that invokes UB for msb all ones.
The right number of relevant bits in that case is 1 though (like for
-2 it is 2 and -4 or -3 3 as already computed) - all we care about from that
is that the most significant bit is set (i.e. the number is negative) and
the bits below that should be supplied from the limbs below.
So, the following patch fixes it by special casing it not to invoke UB.
For msb 0 we already have a special case from before (but that is also
different because msb 0 implies the whole number is 0 given the way
bitint_reduce_prec works - even if we have limbs like ..., 0x80000000U, 0U
the reduction can skip the most significant limb and msb then would be
the one below it), so if iprec > 0, we already don't call __builtin_clzll
on 0.
2024-02-13 Jakub Jelinek <jakub@redhat.com>
* soft-fp/bitint.h (FP_FROM_BITINT): If iprec < 0 and msb is all ones,
just set n to 1 instead of using __builtin_clzll (~msb).

The initial heap trampoline implementation was targeting 64b
platforms. As the PR demonstrates this creates an issue where it
is expected that the same symbols are exported for 32 and 64b.
Rather than conditionalize the exports and code-gen on x86_64,
this patch provides a basic implementation of the IA32 trampoline.
This also avoids potential user confusion, when a 32b target has
64b multilibs, and vice versa; which is the case for Darwin.

The ia32 _BitInt support revealed a bug in floatbitint?d.c.
As can be even guessed from how the code is written in the loop,
the intention was to set inexact to non-zero whenever the remainder
after division wasn't zero, but I've ended up just checking whether
the 2 least significant limbs of the remainder were non-zero.
Now, in the dfp/bitint-4.c test in one case the remainder happens
to have least significant 64 bits zero and then the higher limbs are
non-zero; with 32-bit limbs that means 2 least significant limbs are zero
and so the code acted as if it was exactly divisible.
Fixed thusly.
