[sanitizer-coverage] don't emit the CTOR function if nothing has been instrumented llvm-svn: 282465
2016-09-27 09:08:33 +08:00
; Tests that we don't insert __sanitizer_cov_trace_pc_guard_init or some such
; when there is no instrumentation.
; RUN: opt < %s -sancov -sanitizer-coverage-level=3 -sanitizer-coverage-trace-pc-guard -S | FileCheck %s
Reland the "[NewPM] Port Sancov" patch from rL365838. No functional changes were made to the patch since then. -------- [NewPM] Port Sancov This patch contains a port of SanitizerCoverage to the new pass manager. This one's a bit hefty. Changes: - Split SanitizerCoverageModule into 2 SanitizerCoverage for passing over functions and ModuleSanitizerCoverage for passing over modules. - ModuleSanitizerCoverage exists for adding 2 module level calls to initialization functions but only if there's a function that was instrumented by sancov. - Added legacy and new PM wrapper classes that own instances of the 2 new classes. - Update llvm tests and add clang tests. llvm-svn: 367053
