Working on a problem where var-tracking started to spend more time
after LRA is switched on, I found that LRA creates significant #
clobbers for x86 code (I saw 20% of all insns). Clobbers are created for
correct live range analysis in LRA in cases when matching pseudos of

Hello world,
the attached patch, which is not in its final stage, implements some
warnings for index variables of DO loops. For the following situations,
errors/warnings are issued when an index loop variable is
passed as an actual argument:

Thanks, Andreas! The validator did not complain -- which shows

Hi,
this patch makes optimizer to predict this-field to be optimized out.
The main motivation for this is to make destructors that only calls destructor

The following patch fixes PR55106. A value in GENERAL_REGS is
inherited into a move with destination pseudo of SSE_REGS. It results
into secondary move for which inheritance is tried again an again. It
means cycling LRA passes.
The patch was successfully bootstrapped on x86/x86-64.

The code changes seem fine, but I don't think a testcase should depend on
the details of what system strings.h declares (or even that it exists)
like that. If you want a system header declaration, add a header to the
testsuite that uses #pragma GCC system_header to be sure it's handled as
Hi Vladimir,
There are many trialling white spaces in LRA codes. This patch removes
them.
