+ <dnovillo> jsm28: in your mentor testing, you have the source and build
+ tree available for make check? or it's a pure installed-tree test?
+ <jsm28> dnovillo: Source tree, install tree, no build tree.
+ <dnovillo> jsm28: so, you run make check on top of the source tree or copy
+ the */testsuite trees to a testing area?
+ <jsm28> Create a site.exp and do runtest in a temporary directory. runtest
+ is pointed to the source tree to find sources.
+ <jsm28> For cross testing for GNU/Linux targets, the temporary directory is
+ mounted at the same path on host and target.
+ <dnovillo> jsm28: thanks. i guess i'll have to find the slice of the
+ source tree i need to copy.
+ <dnovillo> jsm28: for libstdc++ do you write a different site.exp?
+ <dnovillo> i noticed that it generates a different site,exp there.
+ <jsm28> The site.exp is mostly the same for all testsuites (so includes
+ settings that only some testsuites use).
+ <dnovillo> ok, thanks.
+ <dnovillo> and when you say "pointed to the source tree" you mean "set
+ srcdir /path/to/top/of/gcc" ?
+ <dnovillo> (in site.exp)
+ <jsm28> The GDB testsuite requires that you run the GDB testsuite's
+ configure script in the temporary directory where you will run runtest.
+ I don't think any GCC testsuites we use have requirements like that.
+ <jsm28> dnovillo: --srcdir option to runtest.
+ <dnovillo> ah, yes.
+ <jsm28> (and --tool, --target_board etc.)
+ <dnovillo> right
+ <dnovillo> since i'm distributing the tests. i want each node to only do a
+ bunch of files. this means that i either use 'tool.exp=file-pattern' or
+ simply copy the subset of files i want tool.exp to find.
+ <dnovillo> i chose the second approach, but that breaks in a handful of
+ cases that need files from other sub-directories.
+ <dnovillo> like g++.dg gcc.dg using stuff from c-c++-common.
+ <dnovillo> for libstdc++, the possibilities for splitting are enormous as
+ it has many directories.
+ <dnovillo> but i'm not setting it right. runtest runs without even trying
+ to test anything.
+ <dnovillo> i'm not having it pick up the right driver.
+ <jsm28> Probably all .exp files should be copied to anywhere running
+ testsuites, since some read .exp files from other directories.
+ <dnovillo> jsm28: that could be it too. it's irritating that libstdc++
+ does not even error out. runtest just does nothing and returns 0.
