Bug 196689 – app-emulation/qemu-user-0.9.0: Doesn't compile: "error: unable to find a register to spill in class 'GENERAL_REGS'": gcc 4

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Alexander Skwar 2007-10-22 06:51:58 UTC]

While trying to emerge app-emulation/qemu-user-0.9.0, I got this error:

[...]

Did I get this error, because I'm using gcc 4.2.2? If so, this seems to be a regression of bug #122228, I'd think.

Complete build log will be attached.

With gcc 3.4.6, it compiles just fine. So that's really a regression of bug #122228.

[Comment 3 Luca Barbato 2009-03-07 15:48:54 UTC]

now qemu-0.10 builds with gcc-4 please test and close if everything works.
