| # VLE Instructions for Improving Interrupt Handler Efficiency (e200z760RM.pdf) |
| # Original Engineering Bullet (EB696.pdf) contains two writings of load instructions |
| # and has no ones for MCSRRs. |
| |
| # e_lmvgprw, e_stmvgprw - load/store multiple volatile GPRs (r0, r3:r12) |
| # e_lmvsprw, e_stmvsprw - load/store multiple volatile SPRs (CR, LR, CTR, and XER) |
| # e_lmvsrrw, e_stmvsrrw - load/store multiple volatile SRRs (SRR0, SRR1) |
| # e_lmvcsrrw, e_stmvcsrrw - load/store multiple volatile CSRRs (CSRR0, CSRR1) |
| # e_lmvdsrrw, e_stmvdsrrw - load/store multiple volatile DSRRs (DSRR0, DSRR1) |
| # e_lmvmcsrrw, e_stmvmcsrrw - load/store multiple volatile MCSRRs (MCSRR0, MCSRR1) |
