Rafael Espindola ce93beb88e Use assembler expressions to lay out the EH LSDA. ... Rely on the assembler to finalize the layout of the DWARF/Itanium exception-handling LSDA. Rather than calculate the exact size of each thing in the LSDA, use assembler directives: To emit the offset to the TTBase label: .uleb128 .Lttbase0-.Lttbaseref0 .Lttbaseref0: To emit the size of the call site table: .uleb128 .Lcst_end0-.Lcst_begin0 .Lcst_begin0: ... call site table entries ... .Lcst_end0: To align the type info table: ... action table ... .balign 4 .long _ZTIi .long _ZTIl .Lttbase0: Using assembler directives simplifies the compiler and allows switching the encoding of offsets in the call site table from udata4 to uleb128 for a large code size savings. (This commit does not change the encoding.) The combination of the uleb128 followed by a balign creates an unfortunate dependency cycle that the assembler must sometimes resolve either by padding an LEB or by inserting zero padding before the type table. See PR35809 or GNU as bug 4029. Patch by Ryan Prichard! llvm-svn: 324749		2018-02-09 17:00:25 +00:00
