Hi all,
After days spent trying to get a clean gmake check run, I am down to the
last few failures. They are all related to the PCH tests, and they all
fail the same way: "largefile.c:1: fatal error: had to relocate PCH".
Previously, *all* PCH tests were failing but I crafted a host file
that uses MAP_FIXED and now only this one test fails. However, if I
pretend that mmap() doesn't exist in ggc-page.c and fall back on
valloc, then everything passes. But the comments say that is not the
prefered solution. My question is: exactly what kind of penalty would
I pay if I forced the use of valloc() versus using mmap?
Any advice greatly appreciated.
