# RUN: ld64.lld -arch arm64 -o %t %s \
Have one version of libSystem for each arch. NFC. An upcoming commit will change how we choose to reference a dylib. Currently dylibs are only given an LC_LOAD_DYLIB in the final image if an atom is used. This is different from ld64 which adds the load command when the dylib is referenced on the cmdline. In order to change this behaviour, we need libSystem.yaml to actually contain a mach header so that it is parsed as a dylib, instead of currently being parsed as a normalised file. To get a mach header, we also require an arch, so now we have one libsystem per arch and all the tests have been updated to choose the correct one. llvm-svn: 278372

Parsed alignment should be a power of 2. The .o path always makes sure to store a power of 2 value in the Section alignment. However, the YAML code didn't verify this. Added verification and updated all the tests which had a 3 but meant to have 2^3. llvm-svn: 264228

Don't bypass the GOT for delta32toGOT references. The gcc_except_tab was generating these references to point to the typeinfo in the data section. gcc_except_tab also had the DW_EH_PE_indirect flag set which means that at runtime we are going to dereference this entry as if it is in the GOT.
