my problem is very simple. I'm uisng GCC for mips, and , I have to do a small part of the code in assembly
I have my $(gp) register correctly set to the _gp section -in the midle of the sda section
I have one variable defined like that
.sdata usbMaxPipeNum: .word 0xFFFFFFFF
and now, in my source, I would like to load $t8 with the content of usbMaxPipeNum, using the gp relative adressing I tried lw $t8, (usbMaxPipeNum) $(gp) the result is Error: illegal operands `lw $t8,usbMaxPipeNum $(gp)'
I tried to add .extern _gp in the .sdata section and then lw $t8, (usbMaxPipeNum - _gp) $(gp) the result is illegal operands `lw $t8,(usbMaxPipeNum-_gp)$(gp)'
what is the correct syntax to do what I want ? thanks in advance for your help
