[llvm-dev] Q about msan : mapping 4TB

[Stefan Teleman via llvm-dev]

Hi,

Porting msan to the Cavium T99 chip requires a VMA mapping of 4TB.

The brute-force way of doing this would be by collecting memory segments
that weren't mapped - from the results of the msan test harness - and
creating mapped segments ranges. Lather, rinse, repeat until all the
addressable segments are mapped in msan.h.

But I was wondering if there isn't a more efficient way of accomplishing
this mapping.

Any help/suggestions/ideas will be greatly appreciated.

Thank you.
