From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! --- arch/ia64/scripts/check-gas | 15 +++++++++ arch/ia64/scripts/check-gas-asm.S | 2 ++ arch/ia64/scripts/check-model.c | 1 + arch/ia64/scripts/check-segrel.S | 4 +++ arch/ia64/scripts/check-segrel.lds | 11 +++++++ arch/ia64/scripts/check-serialize.S | 2 ++ arch/ia64/scripts/check-text-align.S | 6 ++++ arch/ia64/scripts/toolchain-flags | 53 +++++++++++++++++++++++++++++ arch/ia64/scripts/unwcheck.py | 64 ++++++++++++++++++++++++++++++++++++ 9 files changed, 158 insertions(+) create mode 100755 arch/ia64/scripts/check-gas create mode 100644 arch/ia64/scripts/check-gas-asm.S create mode 100644 arch/ia64/scripts/check-model.c create mode 100644 arch/ia64/scripts/check-segrel.S create mode 100644 arch/ia64/scripts/check-segrel.lds create mode 100644 arch/ia64/scripts/check-serialize.S create mode 100644 arch/ia64/scripts/check-text-align.S create mode 100755 arch/ia64/scripts/toolchain-flags create mode 100755 arch/ia64/scripts/unwcheck.py (limited to 'arch/ia64/scripts') diff --git a/arch/ia64/scripts/check-gas b/arch/ia64/scripts/check-gas new file mode 100755 index 000000000000..2499e0b2243d --- /dev/null +++ b/arch/ia64/scripts/check-gas @@ -0,0 +1,15 @@ +#!/bin/sh +dir=$(dirname $0) +CC=$1 +OBJDUMP=$2 +tmp=${TMPDIR:-/tmp} +out=$tmp/out$$.o +$CC -c $dir/check-gas-asm.S -o $out +res=$($OBJDUMP -r --section .data $out | fgrep 00004 | tr -s ' ' |cut -f3 -d' ') +rm -f $out +if [ $res != ".text" ]; then + echo buggy +else + echo good +fi +exit 0 diff --git a/arch/ia64/scripts/check-gas-asm.S b/arch/ia64/scripts/check-gas-asm.S new file mode 100644 index 000000000000..010e1d227e5d --- /dev/null +++ b/arch/ia64/scripts/check-gas-asm.S @@ -0,0 +1,2 @@ +[1:] nop 0 + .xdata4 ".data", 0, 1b-. diff --git a/arch/ia64/scripts/check-model.c b/arch/ia64/scripts/check-model.c new file mode 100644 index 000000000000..e1d4e86e3d63 --- /dev/null +++ b/arch/ia64/scripts/check-model.c @@ -0,0 +1 @@ +int __attribute__ ((__model__ (__small__))) x; diff --git a/arch/ia64/scripts/check-segrel.S b/arch/ia64/scripts/check-segrel.S new file mode 100644 index 000000000000..3be4e3dbeb83 --- /dev/null +++ b/arch/ia64/scripts/check-segrel.S @@ -0,0 +1,4 @@ + .rodata + data4 @segrel(start) + .data +start: diff --git a/arch/ia64/scripts/check-segrel.lds b/arch/ia64/scripts/check-segrel.lds new file mode 100644 index 000000000000..1c2f13e181d0 --- /dev/null +++ b/arch/ia64/scripts/check-segrel.lds @@ -0,0 +1,11 @@ +SECTIONS { + . = SIZEOF_HEADERS; + .rodata : { *(.rodata) } :ro + . = 0xa0000; + .data : { *(.data) } :dat + /DISCARD/ : { *(*) } +} +PHDRS { + ro PT_LOAD FILEHDR PHDRS; + dat PT_LOAD; +} diff --git a/arch/ia64/scripts/check-serialize.S b/arch/ia64/scripts/check-serialize.S new file mode 100644 index 000000000000..0400c106806c --- /dev/null +++ b/arch/ia64/scripts/check-serialize.S @@ -0,0 +1,2 @@ + .serialize.data + .serialize.instruction diff --git a/arch/ia64/scripts/check-text-align.S b/arch/ia64/scripts/check-text-align.S new file mode 100644 index 000000000000..03f586abb734 --- /dev/null +++ b/arch/ia64/scripts/check-text-align.S @@ -0,0 +1,6 @@ + .proc foo + .prologue +foo: .save rp, r2 + nop 0 + .align 64 + .endp foo diff --git a/arch/ia64/scripts/toolchain-flags b/arch/ia64/scripts/toolchain-flags new file mode 100755 index 000000000000..3f0c2adacb70 --- /dev/null +++ b/arch/ia64/scripts/toolchain-flags @@ -0,0 +1,53 @@ +#!/bin/sh +# +# Check whether linker can handle cross-segment @segrel(): +# +CPPFLAGS="" +CC=$1 +OBJDUMP=$2 +READELF=$3 +dir=$(dirname $0) +tmp=${TMPDIR:-/tmp} +out=$tmp/out$$ + +# Check whether cross-segment segment-relative relocs work fine.
