From: Iain Buclaw Date: Sun, 17 May 2020 16:49:19 +0000 (+0200) Subject: libphobos: Backport library fixes from mainline X-Git-Tag: misc/first-auto-changelog-10~35 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=999c80acfdd890b789678c989c3d740969c14d20;p=thirdparty%2Fgcc.git libphobos: Backport library fixes from mainline - core.cpuid has been fixed to not use i7 detection on AMD processors. - std.net.curl has been fixed to correctly handle HTTP/2 status lines. - std.zip has had a test fixed to not rely on unzip being installed. libphobos/ChangeLog: PR d/95166 * libdruntime/core/cpuid.d (cpuidX86): Do not use i7 detection on AMD processors. (hasCPUID): Fix deprecated asm syntax. PR d/95167 * src/std/zip.d (unittest): Skip test if unzip is not installed. PR d/95168 * src/std/net/curl.d (HTTP.onReceiveHeader): Move status line parsing to ... (HTTP.parseStatusLine): ... here. New function. Add support for parsing HTTP/2 status lines. --- diff --git a/libphobos/ChangeLog b/libphobos/ChangeLog index 22fac14a4bcc..0494ad890a97 100644 --- a/libphobos/ChangeLog +++ b/libphobos/ChangeLog @@ -1,3 +1,19 @@ +2020-05-17 Iain Buclaw + + PR d/95166 + * libdruntime/core/cpuid.d (cpuidX86): Do not use i7 detection on AMD + processors. + (hasCPUID): Fix deprecated asm syntax. + + PR d/95167 + * src/std/zip.d (unittest): Skip test if unzip is not installed. + + PR d/95168 + * src/std/net/curl.d (HTTP.onReceiveHeader): Move status line parsing + to ... + (HTTP.parseStatusLine): ... here.
