Summary: Finish dependency file support
Product: clang
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: preprocessor
AssignedTo: [email protected]

clang is still missing various things needed for full dependency file
generation support.
1. Change -M* options to be sane and force driver to convert -M* to the sane
set.
2. Support -M, -MG, -MM, -MQ.
3. Some corner cases differ vs gcc. For example:
--
ddun...@lordcrumb:tmp$ rm -f foo && xcc -S -MD -MF foo -m32 -o y -x c
/dev/null; cat foo
y.o: /dev/null
ddun...@lordcrumb:tmp$ rm -f foo && gcc -S -MD -MF foo -m32 -o y -x c
/dev/null; cat foo
y: /dev/null
ddun...@lordcrumb:tmp$ rm -f foo && xcc -E -MD -MF foo -m32 -o y -x c
/dev/null; cat foo
cat: foo: No such file or directory
ddun...@lordcrumb:tmp$ rm -f foo && gcc -E -MD -MF foo -m32 -o y -x c
/dev/null; cat foo
null.o: /dev/null
