Bug ID: 22694
Summary: Sanitizer blacklist broken with preprocessed source
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt
Assignee: [email protected]

Classification: Unclassified

# 1 "1.cc"
# 1 "<built-in>" 1
# 1 "<built-in>" 3
# 344 "<built-in>" 3
# 1 "<command line>" 1
# 1 "<built-in>" 2
# 1 "1.cc" 2
void f() {}

define void @_Z1fv() #0 {
Blacklist did not apply. The code in SanitizerBlacklist.cpp tried to match
"1.ii" against the blacklist.
It looks like we need to use getPresumedLoc instead of getFileLoc, but it may
not be that simple (will we lose macro expansion then?).
