Chris Lattner	e0b1ee937a	Don't attribute in file headers anymore. See llvmdev for the ... discussion of this change. Boy are my fingers tired. ;-) llvm-svn: 45411	2007-12-29 19:59:42 +00:00
Gordon Henriksen	c6f9e0beef	CollectorMetadata and Collector are rejiggered to get along with ... per-function collector model. Collector is now the factory for CollectorMetadata, so the latter may be subclassed. llvm-svn: 44827	2007-12-11 00:30:17 +00:00
Gordon Henriksen	b20ff7f981	CollectorMetadata abstractly describes stack maps for a function. ... It includes: - location and of each safe point in machine code (identified by a label) - location of each root within the stack frame (identified by an offset), including the metadata tag provided to llvm.gcroot in the user program - size of the stack frame (for collectors which want to cheat on stack crawling :) - and eventually will include liveness It is to be populated by back-ends during code-generation. CollectorModuleMetadata aggregates this information across the entire module. llvm-svn: 42418	2007-09-27 22:18:46 +00:00
