Subject: Skip gdb.base/many-headers.exp on Cygwin (submit independently)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b4d3f6cf54e7d821a5a2d165ada951d1f6934a71;p=thirdparty%2Fbinutils-gdb.git

Skip gdb.base/many-headers.exp on Cygwin (submit independently)

When I first wrote this, I didn't have dumper.exe setup, so the
testcase would spend 10 minutes doing the mmap loop thing, and then it
wouldn't create a core dump anyhow.  But with dumper.exe around, the
testcase does generate the core dump, and it passes cleanly!  So just
skipping isn't right.  I'm inclined to just drop the patch.

I also wonder whether using native Win32 VirtualAlloc would be a lot
faster than Cygwin mmap...
