Hi All,
I am doing a port of GCC for a small internal processor and I have a question
about function parameter passing. I am allocating space for function
parameters on the frame (via crtl->outgoing_args_size) and want gcc to use this
space via frame pointer manipulation, not stack pointer ma

It's a stack probe, making sure that there is enough stack space. Its
only purpose is to provide a SE

Hi,
I am trying to use gcc-6.3.0 to cross-compile a kernel for an old mips64
platform, an SGI Onyx2 ("IP27"), however, it looks like a large number of
functions within the compiled code are getting a common instruction emitted at
the top of the function that breaks this particular machine.

TSan support was contributed to LLVM by a student working at one of the US
National Labs a while back. I helped him with some of the PPC assembly
programming. To my knowledge this is working, but I haven't tested this with
GCC. Do you think we want to change the configuration for GCC this late

I've noticed today there is tsan_rtl_ppc64.S file since the latest

Hi,
I have successfully bootstrapped and installed a release version of gcc
6.3.0.
As I have read at the end of the installation instructions I send you the
following information:

If yes, then libsanitizer/configure.tgt should be changed to reflect that
change.
