commit cd5603a4767277a29d3e67a9c3f2a5d2129cd973

Author: Sterling Augustine <saugustine@google.com>
|

|
||||
Add --unwindlib=[libgcc|compiler-rt] to parallel --rtlib= [take 2]
|
||||
|
||||
"clang++ hello.cc --rtlib=compiler-rt"
|
||||
|
||||
now can works without specifying additional unwind or exception
|
||||
handling libraries.
|
||||
|
||||
This reworked version of the feature no longer modifies today's default
|
||||
unwind library for compiler-rt: which is nothing. Rather, a user
|
||||
can specify -DCLANG_DEFAULT_UNWINDLIB=libunwind when configuring
|
||||
the compiler.
|
||||
|
||||
This should address the issues from the previous version.
|
||||
|
||||
Update tests for new --unwindlib semantics.
