Andrew Pinski could you please share with me requirements needed for strict

Actually I do not understand why read-write cycle is needed if no "read" or

Try -mprefer-vector-width=128,256-bit vectorization is not helpful for 548

This is incorrect. The code will treat the value of _binary_a_c_size as an

Also it is wrong for a person to assume a normal C variable could be SHN_ABS;
that is the bug here. It is a bug in the user code.
I showed up to fix it by using an top level inline-asm.

volatile and packed on strict alignment targets are interesting to say the
least.
packed makes the alignment to 1 too.

Hi,
This is the last of the small QA improvements to the dejagnu test files
for running the D2 testsuite.
This patch adds cases for JSON and D header file generation flags in the
testsuite, and sets up the test accordingly to only compile, then check
that the expected output file exists.

Hi!
The following testcase ICEs, because the FE when processing the statement
expression changes the .VEC_CONVERT internal fn CALL_EXPR into .PHI call.
That is because the internal fn call is recorded in the base.u.ifn
