Bootstrapped and regression tested on x86_64-linux-gnu, and committed. Regards, Iain. --- 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.
