--- Comment #5 from Zdenek Sojka <zsojka at seznam dot cz> --- If anyone is interested in what architecutres are affected without looking at the source code, there are rough statistics of ICEs encountered since it first appeared: ICEs count | switch 21 -march=bdver3 160 -mtune=amdfam10 134 -mtune=barcelona 153 -mtune=bdver1 129 -mtune=bdver2 176 -mtune=bdver3 145 -mtune=bdver4 The reason for so low -march= count is that I am no longer using the -march= switch. Other architectures are likely not affected.
