10 years agoStopgap fix for finding module for a file mapped in the VFS
Ben Langmuir [Fri, 23 May 2014 18:15:47 +0000 (18:15 +0000)]
Stopgap fix for finding module for a file mapped in the VFS

If we lookup a path using its 'real' path first, we need to ensure that
when we run header search we still use the VFS-mapped path or we will
not be able to find the corresponding module for the header.

The real problem is that we tie the name of a file to its underlying
FileEntry, which is uniqued by inode, so we only ever get the first name
it is looked up by. This doesn't work with modules, which rely on a
specific file system structure.  I'm hoping to have time to write up a
proposal for fixing this more permanently soon, but as a stopgap this
patch updates the name of the file's directory if it comes from a VFS
mapping.

paths into it (that is, if the current block is dead, the block containing the

GlobalValue: Testcase for hidden visibility and local linkage

This is a testcase for r209227, a change in LLVM that automatically sets
visibility to default when the linkage is changed to local (rather than
asserting).

What this testcase triggers is hard to reproduce otherwise:  the
`GlobalValue` is created (with non-local linkage), the visibility is set
to hidden, and then the linkage is set to local.
