...range of instructions covering the call to foo() has an action table index of 0, meaning a cleanup. Here is the output of ToT clang on this code: __Z3barv: ## @_Z3barv Ltmp5: .cfi_startproc .cfi_personality 155, ___gxx_personality_v0 Leh_func_begin0: .cfi_lsda 16, Lexception0 ## BB#0: ## %entry pushq %rbp Ltmp6: .cfi_def_cfa_offset 16 Ltmp7: .cfi_offset %rbp, -16 movq %rsp, %rbp Ltmp8: .cfi_def_cfa_register %rbp subq $80, %rsp leaq -8(%rbp), %rdi callq __ZN3BobC1Ev leaq -16(%rbp), %rdi callq __ZN3BobC1Ev leaq -24(%rbp), %rdi ca...

John, I'm still not sure what you're talking about, I have included the assembly output from two compilations, one with a user explicit catch-all, one with only an implicit cleanup, the DWARF Action Table and Types Table are absolutely identical, as are the indexes used to reference the Action Table from the region maps. -Peter Lawrence.

...tches to latest llvm (svn build) lately but i have one problem as far as the Exception Handling mechanism is concerned. It seems that there are no Exception Tables generated any more such as the one below: .section .gcc_except_table,"a", at progbits .align 4 GCC_except_table0: .Lexception0: .byte 255 # @LPStart Encoding = omit .byte 3 # @TType Encoding = udata4 .uleb128 41 # @TType base offset .byte 3 # Call site Encoding = udata4 .uleb128 39 # Call site table...

...; as the one below: got some example bitcode for which you see this (or, rather, don't see this since the problem is that you are not seeing exception tables)? Ciao, Duncan. > > .section .gcc_except_table,"a", at progbits > .align 4 > GCC_except_table0: > .Lexception0: > .byte 255 # @LPStart Encoding = omit > .byte 3 # @TType Encoding = udata4 > .uleb128 41 # @TType base offset > .byte 3 # Call site Encoding = udata4 > .uleb128 39...
