Hi, I was looking at the ARM ABI docs(http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044e/IHI0044E_aaelf.pdf) and they mention. "A binary file may use REL or RELA relocations or a mixture of the two (but multiple relocations for the same address must use only one type)." Does LLVM emit rel/rela relocations with ARM ? Any tests ? Thanks Shankar Easwaran -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by the Linux Found...

Hi, I noticed that klibc started crashing on 64-bit MIPS and in my quest to fix the bug I got a bit carried away and fixed a few other things as well. Here are various miscellaneous MIPS patches, although the first patch is the important one. Thanks, James *** BLURB HERE *** James Cowgill (5): mips64: compile with -mno-abicalls mips: use -Ttext-segment when linking shared library

Hi, Now lld writes relocations to the ".rela" sections only. Mips requires to use the "rel" format. So we need to be able to select format and names of relocation section, names of symbols like __rela_iplt_* / __rel_iplt_*, dynamic table tag DT_RELA / DT_REL. My current idea: - Add two virtual functions DefaultLayout::createDy...

...this is exactly as llvm-objdump does it: we are iterating through sections and in each section we are iterating over relocations (see PrintRelocations() function at https://llvm.org/svn/llvm-project/llvm/trunk/tools/llvm-objdump/llvm-objdump.cpp). However, it does not give us relocation entries in .rela.dyn section. Consider, for instance, the output of "readelf -r /bin/true": $ readelf -r /bin/true Relocation section '.rela.dyn' at offset 0xa80 contains 5 entries: Offset Info Type Sym. Value Sym. Name + Addend 000000604c38 001800000006 R_X86...

Hi Shankar, > Does LLVM emit rel/rela relocations with ARM ? I believe we emit .rel for (32-bit) ARM. Hard-coded in ARMELFObjectWriter.cpp (“HasRelocationAddend”). It seems to be what most toolchains have settled on. AArch64 is .rela always in LLVM, in case it matters. > Any tests ? Well there are tests of what we do, but obvious...

I think the linking context should decide whether to use rel (or) rela. This is also needed if --emit-relocations option is chosen (or) -r option is used. Thoughts ?
