New Revision: 3488
Modified:
trunk/osprey/wgen/wgen_decl.cxx
trunk/osprey/wgen/wgen_stmt.cxx
Log:
The global scope inline assemly code is handled as fake function whose
function name contains the assemble code string, the body of the fake
function is empty. The fake function is not constructed with proper
attributes, especialy the language kind and function type are not correct,
which caused assertion in pre-opt. The fix for now is to set the attributes
to avoid the assertion: language kind to be the same as compiler language
kind, function type to be void return type function.
