[Qemu-devel] [PATCH v9 1/9] tcg: pass down TranslationBlock to tcg_code_gen |
Date: |
Tue, 15 Mar 2016 14:30:16 +0000 |
My later debugging patches need access to the origin PC which is held in
the TranslationBlock structure. Pass down the whole structure as it also
holds the information about the code start point.
