Bug ID: 17911
Summary: Excessive output using clang-cl
Product: clang
Version: trunk
Hardware: PC
OS: Windows XP
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Compiling with clang-cl there is excessive output being produced every time a
macro is encountered. There must be a way developed to turn off all this
output, which is neither a warning or an error. Nobody is going to want to look
through all this output by default. Please either turn this output off by
default ( preferred ) or create a compiler switch to do so.
The output looks like:
--------------------------------------------------------------------------------

'MPL_ASSERT'
#define MPL_ASSERT(pred) BOOST_MPL_ASSERT(pred)

and on and on. This sort of stuff is normally unnecessary.
