Place the LSDA into the TEXT section for ARM platforms. This involves making the encoding indirect, pcrel, and sdata4 instead of an absolute pointer. The references to the type infos are then non-lazy pointers. Revision 98019 changed the encoding of non-lazy pointers to add the symbol to the non-lazy pointer definition if it's a local symbol (otherwise, it's external and set to '0' so that the loader can adjust it to the real value). This paved the way for this change to work on ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98068 91177308-0d34-0410-b5e6-96231b3b80d8
