Package: quemu Severity: important Tags: upstream Hello,
The default build of qemu64 advertises its CPU as something nonsensical such as a Pentuim II (not a 64 bit machine) [1]. This causes GMP's runtime detection of the CPU to fail, leading to gcc failure on some of the build daemon machines [2]. At the moment, GMP has reverted to using compile-time detection of the CPU type. This is not acceptable in the long term because it means: (a) the code may exhibit bugs if the user machine doesn't support opcodes that the build machine does; e.g. build on AMD 10h, run on AMD 11h [3] (b) the code may run at sub-optimal speed on user machines In thread [1], Paolo Bonzini claims [4]: You should use kvm32 and kvm64 instead. This may be a trivial fix for the matter.
