* Fix PR11685 by implementing -ffast-math and its various friends in theChandler Carruth2012-01-021-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | Clang driver. This involves a bunch of silly option parsing code to try to carefully emulate GCC's options. Currently, this takes a conservative approach, and unless all of the unsafe optimizations are enabled, none of them are. The fine grained control doesn't seem particularly useful. If it ever becomes useful, we can add that to LLVM first, and then expose it here. This also fixes a few tiny bugs in the flag management around -fhonor-infinities and -fhonor-nans; the flags now form proper sets both for enabling and disabling, with the last flag winning. I've also implemented a moderately terrifying GCC feature where a language change is also provided by the '-ffast-math' flag by defining the __FAST_MATH__ preprocessor macro. This feature is tracked and serialized in the frontend but it isn't used yet. A subsequent patch will add the preprocessor macro and tests for it. I've manually tested that codegen appears to respect this, but I've not dug in enough to see if there is an easy way to test codegen options w/o relying on the particulars of LLVM's optimizations. llvm-svn: 147434

* Fix PR8639 by making the "argument unused during compilation" less ↵Rafael Espindola2010-12-201-19/+16

| | | | llvm-svn: 105958
* Driver: Add an explicit argument translation phase to the driver itself. We ↵Daniel Dunbar2010-06-111-3/+1

* Driver: Switch to using explicit {getLast,has}ArgNoClaim functions instead ↵Daniel Dunbar2009-11-191-16/+19

* Add stack protector support to clang. This generates the 'ssp' and 'sspreq'Bill Wendling2009-06-281-0/+29
| | | | | | | | function attributes. There are predefined macros that are defined when stack protectors are used: __SSP__=1 with -fstack-protector and __SSP_ALL__=2 with -fstack-protector-all. llvm-svn: 74405
* Add option for AddAllArgsTranslated to control whether output argumentDaniel Dunbar2009-04-261-3/+11

* Driver: Add default for ArgList::hasFlag and simplify implementation.Daniel Dunbar2009-04-071-6/+2
| | | | llvm-svn: 68549
* Driver: Explicitly ignore -fpch-preprocess when using clang, we don'tDaniel Dunbar2009-04-031-0/+9
| | | | | | need to do anything special to support this. llvm-svn: 68403
* Driver: Unbreak ArgList::hasFlag.Daniel Dunbar2009-03-301-1/+1
| | | | | | | - <rdar://problem/6726511> [driver] clang does not have -msoft-float hooked up. llvm-svn: 68044
* Driver: Track which original arguments an arg is derived from, so thatDaniel Dunbar2009-03-291-8/+9
| | | | | | | we can properly claim arguments, even if they have been translated by the tool chain. llvm-svn: 68020
* Driver: Add ArgList::AddAllArgsTranslated; for forwarding options toDaniel Dunbar2009-03-261-0/+13
| | | | | | | tools with the name of the option replace, and arguments rendered separately. llvm-svn: 67753
* Driver: Prep for tool chain specific argument translation.Daniel Dunbar2009-03-251-50/+78
| | | | | | | | | | | | | | | | - Lift ArgList to a base class for InputArgList and DerivedArgList. - This is not a great decomposition, but it does embed the translation into the type system, and keep things efficient for tool chains that don't want to do any translation. - No intended functionality change. Eventually I hope to get rid of tool chain specific translation and have each tool do the right thing, but for now this is the easiest way to match gcc precisely (which is good for testing). llvm-svn: 67676
* Driver: ArgList::getLastArg was in fact returning the first matching arg.Daniel Dunbar2009-03-241-3/+1
| | | | | | | - <rdar://problem/6715818> clang doesn't honor gcc semantic that last -O optimization option wins. llvm-svn: 67628
* Driver: Implement 'missing argument' error.Daniel Dunbar2009-03-221-1/+3
| | | | llvm-svn: 67490
* Driver: Add two option overload for AddAllArgValues.Daniel Dunbar2009-03-201-0/+13
| | | | llvm-svn: 67377
* Driver: Add argument translation utilities to ArgList.Daniel Dunbar2009-03-181-0/+65
| | | | | | | | - Support things like telling which -ffoo -fno-foo option won, and forwarding all arguments matching a certain set of options to the tool. llvm-svn: 67189
* Driver: Fix typo ArgList destructor.Daniel Dunbar2009-03-171-1/+1
| | | | llvm-svn: 67101
* Driver: Add two option form of ArgList::getLastArg.Daniel Dunbar2009-03-171-0/+14
| | | | llvm-svn: 67090
* Add ArgList::MakeArgString and make ArgList::Make* const.Daniel Dunbar2009-03-171-6/+10
| | | | | | | | | - Slightly strange, but the idea is that the ArgList data structure is primarily a list of arguments; we want to allow clients to still add argument strings to an ArgList to avoid worrying about string lifetimes (or unnecessary string copying). llvm-svn: 67086
* Driver: Update ArgList::{hasArg,getLastArg} to optionally claim theDaniel Dunbar2009-03-151-3/+6
