diff tango.patch @ 986:a8cb25d478c4

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use LLVM-style command line (instead of DMD-style) Note: For a backward compatible interface, use the new bin/ldmd script. It supports all old options while passing on anything it doesn't recognize. Some changes caused by this: * -debug and -version are now -d-debug and -d-version due to a conflict with standard LLVM options. * All "flag" options now allow an optional =true/=1/=false/=0 suffix. * Some "hidden debug switches" starting with "--" were renamed because LLVM doesn't care about the number of dashes, so they were conflicting with other options (such as -c). The new versions start with "-hidden-debug-" instead of "--" * --help works, but has a non-zero exit code. This breaks some Tango scripts which use it to test for compiler existence. See tango.patch. Some changes not (directly) caused by this; * (-enable/-disable)-FOO options are now available for pre- and postconditions. * -march is used instead of -m (like other LLVM programs), but -m is an alias for it. * -defaultlib, -debuglib, -d-debug and -d-version allow comma-separated values. The effect should be identical to specifying the same option multiple times. I decided against allowing these for some other options because paths might contain commas on some systems. * -fPIC is removed in favor of the standard LLVM option -relocation-model=pic Bug: * If -run is specified as the last argument in DFLAGS, no error is generated. (Not very serious IMHO)
