the changes in 8cba72177dcd8de5d37177dbaf2347e5c1f0f1e8:

As an example, the paper says 3wb /* Yields an _BitInt(3); two value
bits, one sign bit */.
So I would expect that 0xFwb gives _BitInt(5); four value bits, one
sign bit, but with this implementation I get _BitInt(2).
This is because ResultVal as 4 bits, and getMinSignedBits() inteprets
it as negative and thus says that 1 bit is enough to represent -1.

This corrects the behavior for calculating the bit-width and adds some

OpenMP uses an LLVM bitcode library to implement a GPU runtime library.
In a standard compilation we link this bitcode library into each source

link it late with all the files, but the bitcode library never has the
regular optimization pipeline applied to it so we miss a few

This error was found when analyzing MySQL with CTU enabled.

When there are space characters in the lookup name, the current
delimiter searching strategy will make the file path wrongly parsed.
And when two lookup names have the same prefix before their first space
characters, a 'multiple definitions' error will be wrongly reported.

e.g. The lookup names for the two lambda exprs in the test case are
`c:@S@G@F@G#@Sa@F@operator int (*)(char)#1` and
`c:@S@G@F@G#@Sa@F@operator bool (*)(char)#1` respectively. And their
prefixes are both `c:@S@G@F@G#@Sa@F@operator` when using the first space
character as the delimiter.

Solving the problem by adding a length for the lookup name, making the
index items in the format of `<USR-Length>:<USR File> <Path>`.

---

In the test case of this patch, we found that it will trigger a "triple
mismatch" warning when using `clang -cc1` to analyze the source file
with CTU using the on-demand-parsing strategy in Darwin systems. And
this problem is also encountered in D75665, which is the patch

Yonghong Song [Sat, 12 Mar 2022 19:05:40 +0000 (11:05 -0800)]
[Clang] Fix an unused-but-set-variable warning with volatile variable

For the following code,
    void test() {
        volatile int j = 0;
        for (int i = 0; i < 1000; i++)
                j += 1;
        return;
    }
If compiled with
    clang -g -Wall -Werror -S -emit-llvm test.c
we will see the following error:
    test.c:2:6: error: variable 'j' set but not used [-Werror,-Wunused-but-set-variable]
            volatile int j = 0;
                         ^

This is not quite right since 'j' is indeed used due to '+=' operator.
gcc doesn't emit error either in this case.
Also if we change 'j += 1' to 'j++', the warning will disappear
with latest clang.

Note that clang will issue the warning if the volatile declaration
involves only simple assignment (var = ...).

To fix the issue, in function MaybeDecrementCount(), if the
operator is a compound assignment (i.e., +=, -=, etc.) and the
variable is volatile, the count for RefsMinusAssignments will be
decremented, similar to 'j++' case.

We usually do this by splatting the value into a vector separately.
If the scalar happens to be sign extended, we can continue using a .vx
