This ABI enables to run Linux on ARM MMU-less cores and supports shared libraries to reduce the memory footprint. Without MMU, text and data segments relative distances are different from one process to another, hence the need for a dedicated FDPIC register holding the start address of the data segment. One of the side effects is that function pointers require two words to be represented: the address of the code, and the data segment start address. These two words are designated as "Function Descriptor", hence the "FD PIC" name. On ARM, the FDPIC register is r9 [1], and the target name is arm-uclinuxfdpiceabi. Note that arm-uclinux exists, but uses another ABI and the BFLAT file format; it does not support code sharing. The -mfdpic option is enabled by default, and -mno-fdpic should be used to build the Linux kernel. This work was developed some time ago by STMicroelectronics, and was presented during Linaro Connect SFO15 (September 2015). You can watch the discussion and read the slides [2]. This presentation was related to the toolchain published on github [3], which is based on binutils-2.22, gcc-4.7, uclibc-0.9.33.2, gdb-7.5.1 and qemu-2.3.0, and for which pre-built binaries are available [3]. The ABI itself is described in details in [1]. Our Linux kernel patches have been updated and committed by Nicolas Pitre (Linaro) in July 2017. They are required so that the loader is able to handle this new file type. Indeed, the ELF files are tagged with ELFOSABI_ARM_FDPIC. This new tag has been allocated by ARM, as well as the new relocations involved. The binutils, QEMU and uclibc-ng patch series have been merged recently. [4][5][6] This series provides support for ARM v7 architecture and has been tested on arm-linux-gnueabi without regression, as well as arm-uclinuxfdpiceabi, using QEMU. arm-uclinuxfdpiceabi has more failures than arm-linux-gnueabi, but is quite functional. Are the GCC patches OK for inclusion in master? Changes between v2 and v3: - added doc entry for -mfdpic new option - took Kyrill's comments into account (use "Armv7" instead of "7", code factorization, use preprocessor instead of hard-coding "r9", remove leftover code for thumb1 support, fixed comments) - rebase over recent trunk - patches with changes: 1, 2 (commit message), 3 (rebase), 4, 6, 7, 9, 14 (rebase), 19 (rebase) Changes between v1 and v2: - fix GNU coding style - exit with an error for pre-Armv7 - use ACLE __ARM_ARCH and remove dead code for pre-Armv4 - remove unsupported attempts of pre-Armv7/thumb1 support - add instructions in comments next to opcodes - merge patches 11 and 13 - fixed protected visibility handling in patch 8 - merged legitimize_tls_address_fdpic and legitimize_tls_address_not_fdpic as requested Thanks, Christophe.
