| 00:02.57 | roxfan | try "ldr pc, foo" instead |
| 00:03.16 | roxfan | or "ldr pc, =#0xAAAAAAAA" |
| 00:26.39 | tillerman | yes, the first works, and the second of course loads from [pc+XXXX] which is where AAAAAAAA resides in the literal pool |
| 00:27.13 | tillerman | I wish to understand better the distinction between "ldr pc, foo" and "ldr pc, =foo" |
| 00:30.06 | roxfan | the latter tells assembler "put the constant somewhere after this code and generate an instruction to load it" |
| 00:32.22 | tillerman | when foo is a constant, yes |
| 00:32.29 | tillerman | but when its a label, you get the off-by-4 pc load |
| 00:33.04 | roxfan | doubt it |
| 00:33.47 | roxfan | it probably puts the word with foo after your 0xAAAAAAAA |
| 00:44.17 | tillerman | damn you are right: pc+XX -> literal pool entry == address of 0xAAAAAAAA (value of pool label) |
| 00:48.09 | dalias | :) |
| 00:53.23 | tillerman | if you really want to smile... |
| 00:53.37 | tillerman | I'll admit that the reason I didn't notice this early is because of an "ltorg:" |
| 00:53.47 | tillerman | the color made the ".ltorg" not work at all :P |
| 00:53.51 | tillerman | s/color/colon/ |
