When storing a TLS symbol to memory, always use an intermediate register to load it. Otherwise the compiler generates an instruction which couldn't be encoded and we see: ----------------------------->8--------------------------- In file included from gethstent_r.c:34: ../nss/getXXent_r.c: In function '__gethostent_r': ../nss/getXXent_r.c:168:1: error: unrecognizable insn: } ^ (insn 25 24 26 5 (set (mem:SI (plus:SI (reg/f:SI 149 virtual-outgoing-args) (const_int 16 [0x10])) [0 S4 A32]) (plus:SI (reg:SI 25 r25) (reg:SI 174))) "../nss/getXXent_r.c":160 -1 (nil)) during RTL pass: vregs ../nss/getXXent_r.c:168:1: internal compiler error: in extract_insn, at recog.c:2304 In file included from getnetent_r.c:34: ../nss/getXXent_r.c: In function '__getnetent_r': ../nss/getXXent_r.c:168:1: error: unrecognizable insn: } ^ (insn 25 24 26 5 (set (mem:SI (plus:SI (reg/f:SI 149 virtual-outgoing-args) (const_int 16 [0x10])) [0 S4 A32]) (plus:SI (reg:SI 25 r25) (reg:SI 174))) "../nss/getXXent_r.c":160 -1 (nil)) during RTL pass: vregs ../nss/getXXent_r.c:168:1: internal compiler error: in extract_insn, at recog.c:2304 ----------------------------->8--------------------------- Note that this patch is not yet submitted to the GCC's master and gcc-9-branch but will be submitted soon.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
