Subject: Fixes to handle generating the initiateAcc and completeAcc functions a little more... 
X-Git-Tag: m5_2.0_beta1~87^2~89^2~7^2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=485568efa972db7fc27f34708d9bc3a2f19871de;p=gem5.git

Fixes to handle generating the initiateAcc and completeAcc functions a little more cleanly.

arch/alpha/isa/mem.isa:
    Avoid explicitly declaring the Mem variable.  Instead break up the code blocks used to generate the initiate and complete functions.  The templates reflect which operands need to be declared for each function (src, dest, or both).

    Loads use both the EA code and mem acc code for the initiate, and memacc code and postacc code for the complete.
    Stores use both the EA code and mem acc code for the initiate, and only post acc code for the complete.
arch/isa_parser.py:
    Remove hack for mem ops.
