Bug ID: 26836
Summary: [ms] type conversion with a type named with two words
cannot be compiled in if statement
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: andrey.kules...@intel.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
!- the way MS compiler works is logical and explainable, because such behavior
is user friendly.
clang can compile such line:
"if( long(t1) < t2 ) ;"
a little bit confusing for a user that this line cannot be compiled:
"if( unsigned long(t1) < t2 ) ;"
I suppose that this feature might be added to clang under fms-compability
option -!
=========Environment============
Language: c++
OS: Windows
Version: trunk
=========How to reproduce========
void f(int t1, unsigned long t2 )
{
if( unsigned long(t1) < t2 ) ;
}
=========Error===================
>>> clang:
error: variable declaration in condition must have an initializer
if( unsigned long(t1) < t2 ) ;
error: expected ')'
if( unsigned long(t1) < t2 ) ;
>>> MSVC/intel icc compiler: no diagnostics
>>> gcc:
error: expected primary-expression before ‘unsigned’
if( unsigned long(t1) < t2 ) ;
error: expected ‘)’ before ‘unsigned’
