Subject: [PATCH 2/3] TIntermediate::promoteConstantUnion(): fix conversion to
|
|
int8
|
|
|
|
The signedness of type char is implementation-defined in C++. The
|
|
conversion to (signed) int8 currently uses a cast to char, which is
|
|
undefined for negative values when the type char is implemented as
|
|
unsigned. Thus, fix to cast to "signed char", which has the intended
|
|
semantic on all implementations.
|
|
|
|
Fixes #2807
