* Recommit Eric's code to validate ASM string's constraints and modifiers.Bill Wendling2012-10-252-0/+72
| | | | | | | | | | | | | This code checks the ASM string to see if the output size is able to fit within the variable specified as the output. For instance, scalar-to-vector conversions may not really work. It's on by default, but can be turned off with a flag if you think you know what you're doing. This is placed under a flag ('-Wasm-operand-widths') and flag group ('-Wasm'). <rdar://problem/12284092> llvm-svn: 166737

* Teach the PCH validator to check the preprocessor options, especiallyDouglas Gregor2012-10-243-7/+131
| | | | | | | | | | | | | | | the macros that are #define'd or #undef'd on the command line. This checking happens much earlier than the current macro-definition checking and is far cleaner, because it does a direct comparison rather than a diff of the predefines buffers. Moreover, it allows us to use the result of this check to skip over PCH files within a directory that have non-matching -D's or -U's on the command line. Finally, it improves the diagnostics a bit for mismatches, fixing <rdar://problem/8612222>. The old predefines-buffer diff'ing will go away in a subsequent commit. llvm-svn: 166641

* [analyzer] Replace -analyzer-no-eagerly-trim-egraph with graph-trim-interval.Jordan Rose2012-10-234-13/+17
| | | | | | | | | | | | | After every 1000 CFGElements processed, the ExplodedGraph trims out nodes that satisfy a number of criteria for being "boring" (single predecessor, single successor, and more). Rather than controlling this with a cc1 option, which can only disable this behavior, we now have an analyzer-config option, 'graph-trim-interval', which can change this interval from 1000 to something else. Setting the value to 0 disables reclamation. The next commit relies on this behavior to actually test anything. llvm-svn: 166528
