Douglas Gregor 4ad3da2843 Entering the main source file in the preprocessor can fail if the 
source file has been changed. Handle that failure more gracefully.

Douglas Gregor 22fde23b6e Check the inode in addition to size and modification time to determine 
whether a file has changed since it was originally read.

Douglas Gregor 6597f59506 Use a simple diagnostic (file modified) when we detect that a file has 
changed, rather than trying to point out how it changed. The "why"
doesn't matter.

Jeffrey Yasskin c4e3f05380 Fix a false-positive memory leak in code using RemoveFileOnSignal(). Because 
libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

Douglas Gregor 82752ec843 Teach SourceManager's content cache to keep track of whether its 
buffer was invalid when it was created, and use that bit to always set
the "Invalid" flag according to whether the buffer is invalid. This
ensures that all accesses to an invalid buffer are marked invalid,
improving recovery.

Bob Wilson c953bca10b Remove redundant writeback flag from ARM address mode 6. Also remove the 
optional register update argument, which is currently unused -- when we add
support for that, it can just be a separate operand.

that occur in constructors (on the unwind path).

Chris Lattner 8fce3dddfa reapply r98656 unmodified, which exposed the asmprinter not 
handling constant unions.

 2010-03-16 21:25:55 +00:00
Johnny Chen 71ab18bdd5 Disambiguate the *_UPD and * variants by specifying the writeback flag as 1. 
This is for the disassembly work.

There are cases where this is not possible, for example, A8.6.53 LDM Encoding T1.
In such case, we'll use an adhoc approach to deduce the Opcode programmatically.
