New Revision: 103080
URL: http://llvm.org/viewvc/llvm-project?rev=103080&view=rev
Log:
add a new --print-diagnostic-categories option, which causes the driver to
print out all of the category numbers with their description. This is useful
for clients that want to map the numbers produced by
--fdiagnostics-show-category=id to their human readable string form. The
output is simple but utilitarian:
$ clang --print-diagnostic-categories
1,Format String
2,Something Else
This implements rdar://7928193
