``` part.phdrs = script->hasPhdrsCommands() ? script->createPhdrs() : createPhdrs(part); ``` createPhdrs() allocates a PT_PHDR and a PF_R PT_LOAD, which will be deleted later in LinkerScript::allocateHeaders, but leave a gap between the program headers and the first section. Don't allocate the segments to avoid the gap. PT_INTERP is likely not needed as well. Reviewed By: ruiu Differential Revision: https://reviews.llvm.org/D67324 llvm-svn: 371398
