It is available on most + Cortex-A8 and -A9 ARMv7 processors. diff --git a/qemu-@QEMUTYPE@-@NAME@ b/qemu-@QEMUTYPE@-@NAME@ new file mode 100755 index 0000000..63b21d7 --- /dev/null +++ b/qemu-@QEMUTYPE@-@NAME@ @@ -0,0 +1,10 @@ +#!/bin/sh + +DEB_HOST_ARCH='@DEB_HOST_ARCH@' +DEB_HOST_ARCH_CPU='@DEB_HOST_ARCH_CPU@' +DEB_HOST_ARCH_BITS='@DEB_HOST_ARCH_BITS@' +DEB_HOST_MULTIARCH='@DEB_HOST_MULTIARCH@' +DEB_HOST_MULTIARCH_CPU='@DEB_HOST_MULTIARCH_CPU@' +QEMU_EXTRA='@QEMU_EXTRA@' + +exec @QEMU@ "$@" diff --git a/refresh-package b/refresh-package new file mode 100755 index 0000000..ce6e505 --- /dev/null +++ b/refresh-package @@ -0,0 +1,210 @@ +#!/usr/bin/perl -w +undef $/; +my $DEB_HOST_MULTIARCH = + ( split /\n/, qx/dpkg-architecture -qDEB_HOST_MULTIARCH/ )[0]; +my $DEB_HOST_ARCH = ( split /\n/, qx/dpkg-architecture -qDEB_HOST_ARCH/ )[0]; +my $DEB_HOST_ARCH_BITS = + ( split /\n/, qx/dpkg-architecture -qDEB_HOST_ARCH_BITS/ )[0]; +my $DEB_HOST_ARCH_CPU = + ( split /\n/, qx/dpkg-architecture -qDEB_HOST_ARCH_CPU/ )[0]; +my $DEB_HOST_MULTIARCH_CPU = $DEB_HOST_MULTIARCH; +$DEB_HOST_MULTIARCH_CPU =~ s/^([^-]+?)-.*$/$1/g; + +my $version = ( split /\n/, qx/dpkg-parsechangelog --show-field Version/ )[0]; + +sub file_replace { + my ( $f, $name, $lcname ) = @_; + my $foutname = $f; + $foutname =~ s/[@]NAME[@]/$name/; + $foutname =~ s/[@]LCNAME[@]/$lcname/; + open IN, "; + close IN; + + s/[@]NAME[@]/$name/g; + s/[@]LCNAME[@]/$lcname/g; + s/[@]DEB_HOST_MULTIARCH[@]/$DEB_HOST_MULTIARCH/g; + open OUT, ">debian/$foutname" + or die "Can't write debian/$foutname: $!\n"; + print OUT; + close OUT; +} + +my $control; + +my $ctemplate; +my $cfilename = 'test-@NAME@.c'; +open( my $fctemplate, '<', $cfilename ) or die "cannot open file $cfilename"; +{ + local $/ = undef; + $ctemplate = <$fctemplate>; +} +close($fctemplate); + +# dpkg-shlibdeps now looks inside, but is ok with an empty file. +system("touch debian/control"); + +my @control_in; +open IN, "; +@control_in = grep !/^\s*$/s, split /\n\s*\n/s; +close IN; + +my @controltest_in; +open IN, "; +@controltest_in = grep !/^\s*$/s, split /\n\s*\n/s; +close IN; + +open ISA_LIST, "; +close ISA_LIST; +my %archlist; + +my @structs; +foreach my $block ( split /\n\s*\n/s ) { + my $lastfield = undef; + my %data = (); + foreach ( split /\n/s, $block ) { + next if /^#.*/; + next if /^\s*$/; + if (/^([^\s:]+?)\s*:\s*(.*?)\s*$/) { + $key = $1; + $value = $2 // ''; + $data{"$key"} = "$value"; + $lastfield = "$key"; + } + elsif (/^(\s+\S.*?)\s*$/) { + $data{$lastfield} .= "\n$1"; + } + + next; + } + if (%data) { + $data{"Package"} = "no" if !exists( $data{"Package"} ); + push @structs, \%data; + } +} + +my $controltest = ''; + +for (@structs) { + my %entry = %$_; + $archlist{ $entry{'Architecture'} } = 1; + my $name = $entry{'Name'}; + my $lcname = lc($name); + $name =~ /^[a-zA-Z0-9\.+_-]+$/ or die "Bad package/isa name: \"$name\".\n"; + my $description = $entry{'Description'}; + $description =~ s/\A\s*\n+//m; + $description =~ s/\A\s+//m; + + if ( $entry{'Package'} =~ /yes/i ) { + my @c = @control_in; + foreach (@c) { + s/[@]NAME[@]/$name/g; + s/[@]LCNAME[@]/$lcname/g; + s/[@]ARCHITECTURE[@]/$entry{'Architecture'}/g; + s/[@]DEB_HOST_MULTIARCH[@]/$DEB_HOST_MULTIARCH/g; + s/[@]DESCRIPTION[@]/$description/g; + $control .= "\n" . $_; + } + } + + open C, '>', "test-$name.c"; + my $test = $entry{'Test'} // "return !__builtin_cpu_supports(\"$lcname\");"; + my $cfile = $ctemplate; + $cfile =~ s/[@]TEST[@]/$test/gm; + $cfile =~ s/[@]NAME[@]/$name/g; + $cfile =~ s/[@]VERSION[@]/$version/g; + my $cdescription = $description; + $cdescription =~ s/"/\"/gm; + $cdescription =~ s/^\s//gm; + $cdescription =~ s/^[.]\n/\n/gm; + $cdescription =~ s/\n/\\n\"\n \"/gm; + $cfile =~ s/[@]DESCRIPTION[@]/$description/g; + $cfile =~ s/[@]CDESCRIPTION[@]/$cdescription/g; + + print C $cfile; + close C; + + for my $qemutype (qw(good bad static-bad static-good)) { + my $qemu = $qemutype; + $qemu =~ s/^static-//g; + if ( exists $entry{ 'qemu-' . $qemu } ) { + my $qemu_extra = ''; + $qemu_extra .= '-static' if ( $qemutype =~ '^static-' ); + + my $finname = 'qemu-' .
