Does it work to write "jump 1f+1" or something?
Unfortunately no :( The assembler will align the address when encoding the
instruction. The only working examples I could think of is using a separated
file, like before, or manually encoding the instruction with a misaligned
address and place it with a `.word` directive... Any preferences, or other
suggestions?
Oof. The assembler is being too helpful. :-P
Perhaps using a different section could solve the fragility issue:
asm("
.pushsection .text.evil
.org 3
...
.popsection
");
(adjusting syntax as necessary for correctness), then it doesn't matter where in the
output assembly the fragment lands.
