That worked, thank you for the tip.

I took the opportunity to request commit access to the GCC repo so that
I can commit the patch myself. Sorry for the delay. I'll commit it as
soon as I get it.
Thank you for the patch review! I'm including below the updated version.

Subject: [PATCH v2] testsuite: Turn errors back into warnings in
arm/acle/cde-mve-error-2.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since commit 2c3db94d9fd ("c: Turn int-conversion warnings into
permerrors") the test fails with errors such as:
FAIL: gcc.target/arm/acle/cde-mve-error-2.c -O0 (test for errors, line 32)
FAIL: gcc.target/arm/acle/cde-mve-error-2.c -O0 (test for errors, line 33)

FAIL: gcc.target/arm/acle/cde-mve-error-2.c -O0 (test for excess errors)
There's a total of 1016 errors. Here's a sample of the excess errors:
Excess errors:
/path/gcc.git/gcc/testsuite/gcc.target/arm/acle/cde-mve-error-2.c:117:31:
error: passing argument 2 of '__builtin_arm_vcx1qv16qi' makes integer from
pointer without a cast [-Wint-conversion]
/path/gcc.git/gcc/testsuite/gcc.target/arm/acle/cde-mve-error-2.c:119:3:
error: passing argument 3 of '__builtin_arm_vcx1qav16qi' makes integer from
pointer without a cast [-Wint-conversion]
/path/gcc.git/gcc/testsuite/gcc.target/arm/acle/cde-mve-error-2.c:121:3:
error: passing argument 3 of '__builtin_arm_vcx2qv16qi' makes integer from
pointer without a cast [-Wint-conversion]
/path/gcc.git/gcc/testsuite/gcc.target/arm/acle/cde-mve-error-2.c:123:3:
error: passing argument 3 of '__builtin_arm_vcx2qv16qi' makes integer from
pointer without a cast [-Wint-conversion]
The test expects these messages to be warnings, not errors. My first try
was to change it to expect them as errors instead. This didn't work, IIUC
because the error prevents the compiler from continuing processing the file
and thus other errors which are expected by the test don't get emitted.
Therefore, add -fpermissive so that the test behaves as it did previously.
Because of the additional line in the header, the line numbers of the
expected warnings don't match anymore so replace them with ".-1" as
suggested by Richard Earnshaw.
Tested on armv8l-linux-gnueabihf.
gcc/testsuite/ChangeLog:
* gcc.target/arm/acle/cde-mve-error-2.c: Add -fpermissive.
