Bug #: 14285
Summary: Bad __DBL_MIN__, __LDBL_MIN__, ... generated
Product: clang
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
When a backend wants to map a 'double' type to a float instance, it indicates
this with setting the 'DoubleFormat' to &llvm::APFloat::IEEESingle
Same thing can be done for 'LongDobleFormat'.
This is mostly fine (the C 'double' type will result in 'f32' llvm-ir type,
but some of the internal generated min/max numbers (__FLT_MIN__, __DBL_MIN__,
...)
contain the wrong suffix, such that __DBL_MIN__ will be interpreted as a float
type, in stead of a double type.
