This reverts commit 6e58539659aea0ee621c7e267d825aa82d4e7e96.
This failed in http://lab.llvm.org:8011/#/builders/123/builds/2676. I guess
were're still missing some symbols, but unfortunately the specific error is
masked by a bug in python/lit that hides stderr. This test will have to remain
disabled on Windows until I can get help to debug it further.
This testcase was failing on windows due to missing definitions. This commit
adds definitions of the missing symbols (as absolute symbols) to eliminate the
errors.
This test is failing on some windows bots with an error claiming that it is not
producing output. This appears to be a spurious failure, so I'm disabling on
windows while we investigate rather than reverting.
Adds the EHFrameSplitter and EHFrameEdgeFixer passes to the default JITLink
pass pipeline for ELF/x86-64, and teaches EHFrameEdgeFixer to handle some
new pointer encodings.
Together these changes enable exception handling (at least for the basic
cases that I've tested so far) for ELF/x86-64 objects loaded via JITLink.
