If anybody is interested in what toolchain to use for the sun4u port. ftp://vger.rutgers.edu/pub/linux/Sparc/ultrapenguin-1.0/SRPMS contains these files : sparc64-linux-binutils-2.8.1-1.src.rpm sparc64-linux-gcc-2.7.2.2-2.src.rpm Extract and hand patch the two rpms. (You can omit the linux-specific patches). After this, apply this little patch to gcc : --- config/sparc/sp64-elf.h~ Thu Apr 2 15:22:46 1998 +++ config/sparc/sp64-elf.h Mon Jul 13 16:06:42 1998 @@ -35,12 +35,12 @@ #undef TARGET_VERSION #define TARGET_VERSION fprintf (stderr, " (sparc64-elf)") -/* A v9 compiler with stack-bias, 32 bit integers and 64 bit pointers, - in a Medium/Anywhere code model environment. */ +/* A v9 compiler with stack-bias, 32 bit integers, 64 bit longs and + 64 bit pointers, in a Medium/Anywhere code model environment. */ #undef TARGET_DEFAULT #define TARGET_DEFAULT \ - (MASK_V9 + MASK_ARCH64 + MASK_PTR64 /* + MASK_HARD_QUAD */ \ + (MASK_V9 + MASK_ARCH64 + MASK_LONG64 + MASK_PTR64 + MASK_HARD_QUAD \ + MASK_STACK_BIAS + MASK_MEDANY + MASK_APP_REGS + MASK_EPILOGUE + MASK_FPU) /* __svr4__ is used by the C library */ Cross compile on any FreeBSD/i386 with target as sparc64-elf And here is the ld script I use to link the `kernel' to an address that OpenBoot PROM expects it to be (replace /usr/cross with your $prefix). /* ld script for FreeBSD/sparc64 kernel */ OUTPUT_FORMAT("elf64-sparc", "elf64-sparc", "elf64-sparc") OUTPUT_ARCH(sparc:v9a) ENTRY(_start) SEARCH_DIR(/usr/cross/sparc64-elf/lib); /* Do we need any of these for elf? __DYNAMIC = 0; */ SECTIONS { /* Default load address : IEEE draft std P1275.1 */ . = 0x4000; /* Read-only sections, merged into text segment: */ .interp : { *(.interp) } .hash : { *(.hash) } .dynsym : { *(.dynsym) } .dynstr : { *(.dynstr) } .gnu.version : { *(.gnu.version) } .gnu.version_d : { *(.gnu.version_d) } .gnu.version_r : { *(.gnu.version_r) } .rel.text : { *(.rel.text) *(.rel.gnu.linkonce.t*) } .rela.text : { *(.rela.text) *(.rela.gnu.linkonce.t*) } .rel.data : { *(.rel.data) *(.rel.gnu.linkonce.d*) } .rela.data : { *(.rela.data) *(.rela.gnu.linkonce.d*) } .rel.rodata : { *(.rel.rodata) *(.rel.gnu.linkonce.r*) } .rela.rodata : { *(.rela.rodata) *(.rela.gnu.linkonce.r*) } .rel.got : { *(.rel.got) } .rela.got : { *(.rela.got) } .rel.ctors : { *(.rel.ctors) } .rela.ctors : { *(.rela.ctors) } .rel.dtors : { *(.rel.dtors) } .rela.dtors : { *(.rela.dtors) } .rel.init : { *(.rel.init) } .rela.init : { *(.rela.init) } .rel.fini : { *(.rel.fini) } .rela.fini : { *(.rela.fini) } .rel.bss : { *(.rel.bss) } .rela.bss : { *(.rela.bss) } .rel.plt : { *(.rel.plt) } .rela.plt : { *(.rela.plt) } .init : { *(.init) } =0 .plt : { *(.plt) } .text 0x0000000000404000 : { *(.text) *(.stub) /* .gnu.warning sections are handled specially by elf32.em. */ *(.gnu.warning) *(.gnu.linkonce.t*) } =0 _etext = .; PROVIDE (etext = .); .fini : { *(.fini) } =0 .rodata : { *(.rodata) *(.gnu.linkonce.r*) } .rodata1 : { *(.rodata1) } .data : { *(.data) *(.gnu.linkonce.d*) CONSTRUCTORS } .data1 : { *(.data1) } .ctors : { *(.ctors) } .dtors : { *(.dtors) } .got : { *(.got.plt) *(.got) } .dynamic : { *(.dynamic) } /* We want the small data sections together, so single-instruction offsets can access them all, and initialized data all before uninitialized, so we can shorten the on-disk segment size. */ .sdata : { *(.sdata) } _edata = .; PROVIDE (edata = .); __bss_start = .; .sbss : { *(.sbss) *(.scommon) } .bss : { *(.dynbss) *(.bss) *(COMMON) } _end = . ; PROVIDE (end = .); /* Stabs debugging sections. */ .stab 0 : { *(.stab) } .stabstr 0 : { *(.stabstr) } .stab.excl 0 : { *(.stab.excl) } .stab.exclstr 0 : { *(.stab.exclstr) } .stab.index 0 : { *(.stab.index) } .stab.indexstr 0 : { *(.stab.indexstr) } .comment 0 : { *(.comment) } /* DWARF debug sections.
