llvm dev - May 2009 - [LLVMdev] catch all

Hi,

 that's  right !  catch(all) has extra null arg,

eh_select = tail call i32 (i8*, i8*, ...)*
@llvm.eh.selector.i32(i8* %eh_ptr, i8* bitcast (i32 (...)*
@__gxx_personality_v0 to i8*), i8* null)        ; <i32> [#uses=0]

I have doubt  that  :
the llvm-IR like above are  all translated from catch(all) statement .

Hi,

sorry for  my terible english !

I mean
there are only the  catch(...) statement   can be translate to the LLVM-IR :
 eh_select = tail call i32 (i8*, i8*, ...)* @llvm.eh.selector.i32(i8*
%eh_ptr, i8* bitcast (i32 (...)*  @__gxx_personality_v0 to i8*), i8*
null)

are there any other case can be translate to the same above LLVM-IR ?


best regards
