I cannot find the "mtlr" in "VLEPEM.pdf", but I find the "se_mtlr" in "VLEPEM.pdf". Are they same? Thank you!

Hello,

instructions which starts with e_ or se_ are from VLE instruction set. Instructions without e_ or se_ are BookE instructions.

For more information about BookE instructions, please check the document in the attachment.

I searched the "mtlr" in the "EREFRM_2-0.pdf", but I still cannot find it. Thank you!

Hello,

sorry my mistake. In BookE, there is only mtspr instruction, so it seems mtlr is alias to mtspr instruction, because Link register is also marked as spr x register.

Instruction mtld loads data to link register as well as se_mtlr.

mtlr only has one parameter, but mtspr has two parameter. Thank you!

Hello,

As I wrote you before. mtlr is only mnemonic to mtspr instruction. Please check for example the link below:

PowerPC Instruction Set: mtspr
