2010-06-09Driver: Change Option parsing to always create arguments referring to unaliasedDaniel Dunbar

2010-06-07Driver: Support invoking Clang on .ll or .bc inputs.Daniel Dunbar
- We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o'). It is now possible to do something like: $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ... $ clang -c t.ll -o t.o ... assorted other compile flags ... and expect that the output will be almost* identical to: $ clang -c t.c -o t.o ... assorted other compile flags ... because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend. *: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105584 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-04Driver/Darwin: Model dsymutil properly, as a separate action/tool kind which isDaniel Dunbar
added as the last output step, instead of just hacking it into the link step. - Among other things, this fixes dSYM generation when using multiple -arch options. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105475 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-22Daniel re-educated me about what Alias does and does not do. Turn that off forChandler Carruth
'-fasm' and explicitly map from that flag to -fgnu-keywords in the driver. Turn off the driver in the lexer test for this madness and add a test to the driver that the translation actually works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104428 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-22Driver: When printing a "command was signalled" type of diagnostic, use theDaniel Dunbar
short name of the tool in use, instead of the name of the action that created the command. The practical impact is we now get: clang: error: clang frontend command failed due to signal 6 (use -v to see invocation) instead of: clang: error: assembler command failed due to signal 6 (use -v to see invocation) when clang crashes on a job that uses the integrated assembler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104417 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-05add a new --print-diagnostic-categories option, which causes the driver toChris Lattner
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.

2010-05-04Introduce a limit on the depth of the macro instantiation backtraceDouglas Gregor
printed in a diagnostic, similar to the limit we already have on the depth of the template instantiation backtrace. The macro instantiation backtrace is limited to 10 "instantiated from:" diagnostics; when it's longer than that, we'll show the first half, then say how many were suppressed, then show the second half. The limit can be changed with -fmacro-instantiation-limit=N, and turned off with N=0. This eliminates a lot of note spew with libraries making use of the Boost.Preprocess library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103014 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-20Introduce a limit on the depth of the template instantiation backtraceDouglas Gregor
we will print with each error that occurs during template instantiation. When the backtrace is longer than that, we will print N/2 of the innermost backtrace entries and N/2 of the outermost backtrace entries, then skip the middle entries with a note such as: note: suppressed 2 template instantiation contexts; use -ftemplate-backtrace-limit=N to change the number of template instantiation entries shown This should eliminate some excessively long backtraces that aren't providing any value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101882 91177308-0d34-0410-b5e6-96231b3b80d8
