* [ESan][MIPS] Fix tests struct-simple.cpp on MIPSSagar Thakur2016-09-221-2/+2
| | | | | | | | | For mips assember '#' is the start of comment. We get assembler error messages if # is used in the struct names. Therefore using '$' which works for all architectures. Differential: D24335 Reviewed by: zhaoqin llvm-svn: 282142
* [esan] Add __esan_report for mid-run dataDerek Bruening2016-07-091-0/+6
| | | | | | | | | | | | | | | | | | | | | Summary: Adds a new public interface routine __esan_report() which can be used to request profiling results prior to abnormal termination (e.g., for a server process killed by its parent where the normal exit does not allow for normal result reporting). Implements this for the working-set tool. The cache frag tool is left unimplemented as it requires missing iteration capabilities. Adds a new test.

* [esan|cfrag] Add struct info registrationQin Zhao2016-06-021-6/+69
| | | | | | | | | | | | | | | | | | | | | Summary: Adds StructInfo to CacheFragInfo to match the LLVM's EfficiencySanitizer structs. Uses StructHashMap to keep track of the struct info used by the app. Adds registerStructInfo/unregisterStructInfo to add/remove struct infos to/from StructHashMap. updates test struct-simple.cpp with more C structs.
