Android prelink error by linaro gcc-4.5 + binutils-2.20

by Meng-Hsuan Cheng

Hello list, I'm a developer at 0xlab and focus on toolchain development. While Android WG was working on integrating Linaro toolchain to Android system, we encountered prelink error since there are some empty symbols in symtab produced by toolchain linaro gcc-4.5 + binutils-2.20. The error message is: target Prelink: libc (out/target/product/beagleboard/symbols/system/lib/libc.so) ASSERTION FAILURE external/elfcopy/elfcopy.c:2457: [!(shdr_info[sym->st_shndx].shdr.sh_flags & SHF_ALLOC)] However, we verified it by linaro gcc-4.5 + google binutils-2.19. There is no prelink problem on this toolchain combination. (Google binutils-2.19 is not compatible to linaro gcc-4.5 since some new feature and new instructions used in linaro gcc-4.5). We produced the link map file and traced this problem, the symbols are merged by linker optimization (relax) and empty entires are inserted in symtab. In function elf_link_output_sym at bfd/elflink.c: if (name == NULL || *name == '\0') elfsym->st_name = 0; else if (input_sec->flags & SEC_EXCLUDE) elfsym->st_name = 0; // st_name will be set to emtry else { elfsym->st_name = (unsigned long) _bfd_stringtab_add (finfo->symstrtab, name, TRUE, FALSE); if (elfsym->st_name == (unsigned long) -1) return 0; } When const strings are merged, the bit of SEC_EXCLUDE in input_sec->flags will be set. The bfd elf linker will set the elfsym->st_name to 0. Before binutils-2.19, the merged string is pushed in section 'glue_t' and the path is not be traveled. I think it's not make sense that the address of NOTYPE symbol *not* behind its section. The zero must be not behind section "rodata.str1.1". So I filed a bug in https://bugs.launchpad.net/binutils-linaro/+bug/707487<https://bugs.launchpad.net/binutils-linaro/+bug/707487/+subscribe> . The log is readelf -a libc.so | grep 00000000 | grep -v FILE | grep -v SECTION | grep -v UND 3372: 00000000 0 NOTYPE LOCAL DEFAULT 8 3375: 00000000 0 NOTYPE LOCAL DEFAULT 8 3381: 00000000 0 NOTYPE LOCAL DEFAULT 8 3382: 00000000 0 NOTYPE LOCAL DEFAULT 8 3397: 00000000 0 NOTYPE LOCAL DEFAULT 8 3408: 00000000 0 NOTYPE LOCAL DEFAULT 8 3409: 00000000 0 NOTYPE LOCAL DEFAULT 8 3411: 00000000 0 NOTYPE LOCAL DEFAULT 8 3415: 00000000 0 NOTYPE LOCAL DEFAULT 8 3424: 00000000 0 NOTYPE LOCAL DEFAULT 8 3437: 00000000 0 NOTYPE LOCAL DEFAULT 8 3439: 00000000 0 NOTYPE LOCAL DEFAULT 8 Any comments?

[GIT PULL] omap[34] Thumb-2 support for linux-linaro-2.6.37

by Dave Martin

This patch series enables Thumb-2 support for omap3 and omap4. It is not currently well tested, and is known to be faulty for certain power management operations including power-off suspend when CONFIG_THUMB2_KERNEL is enabled. Note that from the patch series, this subset are temporary workarounds and not likely to be merged upstream: ARM: Add local symbols in relocate_kernel.S to work around gas bugs ARM: omap3: Work around assembler errors in sleep34xx.S ARM: Avoid discarding sections that might have SMP_ON_UP fixups Full description follows.

cpu supported

by Raffaele Recalcati

Any plan for armv5te support? It should compatible to Ubuntu of 30MB that seems possible [http://lists.linaro.org/pipermail/linaro-dev/2011-January/002109.html] . There are a lot of arm9 boards in the world. We have to think that arm9 is the past? Thanks for any reply, Recalcati

Device tree support for 11.05

by Grant Likely

Hi guys, Nicolas, thanks for taking a look at the basic device tree patches. I've fixed up the defects you've pointed out and pushed the fixed versions out to my tree. Other than that, does it look okay to you? With that series it is possible to turn on device tree booting for any arm platform by turning on CONFIG_OF and adding a dt_compat string table to the existing machine_desc. It is far from complete support since it only decodes the kernel parameters, the initrd location and the memory size, but it is enough for others to start playing with the infrastructure. On the u-boot side of things, everything needed to support device tree appears to be complete and working, other than a bug I ran into on systems with memory based at 0. (fix sent to list). Turning on CONFIG_OF_LIBFDT was simple on Tegra, and I expect it will be on the other platforms too. If I were able to get all the supported Linaro platforms modified and tested to support dt booting, would you be okay with picking up the current dt support series and having CONFIG_OF turned on by default for the next Linaro release? There are also some details to nail down with respect to packaging the .dtb files, but I'm working out those details with Loïc. Cheers, g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.

[PATCH] ARM: SAMSUNG: Removing dependency on CONFIG_PM_DEBUG for clock debugging
