From 0cff5836c3f410136e3fdb3e2f9e24bb81dd9a87 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sat, 19 Apr 2014 17:09:24 +0200 Subject: Remove CPU detection and inline asm handling Not needed anymore. I'm not opposed to having asm, but inline asm is too much of a pain, and it was planned long ago to eventually get rid fo all inline asm uses. For the note, the inline asm use that was removed with the previous commits was almost worthless. It was confined to video filters, and most video filtering is now done with libavfilter. Some mpv filters (like vf_pullup) actually redirect to libavfilter if possible. If asm is added in the future, it should happen in the form of external files. --- old-configure | 253 +--------------------------------------------------------- 1 file changed, 2 insertions(+), 251 deletions(-) (limited to 'old-configure') diff --git a/old-configure b/old-configure index ab75ba16c3..c334c7a74c 100755 --- a/old-configure +++ b/old-configure @@ -129,14 +129,6 @@ EOF compile_check $TMPC $@ } -inline_asm_check() { - cat > $TMPC << EOF -int main(void) { __asm__ volatile ($1); return 0; } -EOF - shift - compile_check $TMPC $@ -} - # The following checks are special and should only be used with broken and # non-selfsufficient headers that do not include all of their dependencies. @@ -207,46 +199,6 @@ netbsd() { issystem "NetBSD"; } openbsd() { issystem "OpenBSD"; } win32() { cygwin || mingw32; } -# arch test boolean functions -x86_32() { - case "$host_arch" in - i[3-9]86|k5|k6|k6-2|k6-3|pentium*|athlon*|i586-i686) return 0 ;; - *) return 1 ;; - esac -} - -x86_64() { - case "$host_arch" in - x86_64|amd64) return 0 ;; - *) return 1 ;; - esac -} - -x86() { - x86_32 || x86_64 -} - -ppc() { - case "$host_arch" in - ppc|ppc64|powerpc|powerpc64) return 0;; - *) return 1;; - esac -} - -alpha() { - case "$host_arch" in - alpha*) return 0;; - *) return 1;; - esac -} - -arm() { - case "$host_arch" in - arm*) return 0;; - *) return 1;; - esac -} - # Use this before starting a check echocheck() { echo "============ Checking for $@ ============" >> "$TMPLOG" @@ -776,7 +728,7 @@ if test "$_cc" = auto ; then fi fi -# Determine our OS name and CPU architecture +# Determine our OS name if test -z "$_target" ; then # OS name system_name=$(uname -s 2>&1) @@ -800,41 +752,6 @@ if test -z "$_target" ; then ;; esac - - # host's CPU/instruction set - host_arch=$(uname -p 2>&1) - case "$host_arch" in - i386|sparc|ppc|alpha|arm|mips|vax) - ;; - powerpc) # Darwin returns 'powerpc' - host_arch=ppc - ;; - *) # uname -p on Linux returns 'unknown' for the processor type, - # OpenBSD returns 'Intel Pentium/MMX ("Genuine Intel" 586-class)' - - # Maybe uname -m (machine hardware name) returns something we - # recognize. - - case "$(uname -m 2>&1)" in - x86_64|amd64|i[3-9]86*|k5|k6|k6_2|k6_3|k6-2|k6-3|pentium*|athlon*|i586_i686|i586-i686|BePC) host_arch=i386 ;; - ia64) host_arch=ia64 ;; - macppc|ppc) host_arch=ppc ;; - ppc64) host_arch=ppc64 ;; - alpha) host_arch=alpha ;; - sparc) host_arch=sparc ;; - sparc64) host_arch=sparc64 ;; - parisc*|hppa*|9000*) host_arch=hppa ;; - arm*|zaurus|cats) host_arch=arm ;; - sh3|sh4|sh4a) host_arch=sh ;; - s390) host_arch=s390 ;; - s390x) host_arch=s390x ;; - *mips*) host_arch=mips ;; - vax) host_arch=vax ;; - xtensa*) host_arch=xtensa ;; - *) host_arch=UNKNOWN ;; - esac - ;; - esac else # if test -z "$_target" for i in 2 3; do system_name=$(echo $_target | cut -d '-' -f $i) @@ -851,11 +768,6 @@ else # if test -z "$_target" esac break done - # We need to convert underscores so that values like k6-2 and pentium-mmx can be passed - host_arch=$(echo $_target | cut -d '-' -f 1) - if test $(echo $host_arch) != "x86_64" ; then - host_arch=$(echo $host_arch | tr '_' '-') - fi fi extra_cflags="-I. -D_GNU_SOURCE $extra_cflags" @@ -1019,114 +931,11 @@ echocheck "perl" command_check perl -Mv5.8 -e';' || die "Perl is not functioning correctly or is ancient.
