Subject: Nothing architecturally limits powerpc to high memory.
X-Git-Tag: mit-scheme-pucked-10.1.10~6^2~49
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=1c269815021cdea7e041f35fdf09d5ae108cc19b;p=mit-scheme.git

Nothing architecturally limits powerpc to high memory.

Individual operating systems may, but none that I've encountered.

We may revisit this if we change SVM1 to always work in high memory.
