/* We don't want 0x00 for code alignment because this generates `add.p
|
|
|
|
gr0, gr0, gr0' patterns. Although it's fine as a nop instruction,
|
|
|
|
it has the VLIW packing bit set, which means if you have a bunch of
|
|
|
|
them in a row and attempt to execute them, you'll exceed the VLIW

capacity and fail. This also gets GDB confused sometimes, because

it won't set breakpoints in instructions other than the first of a
|
|
|
|
VLIW pack, so you used to be unable to set a breakpoint in the

|
|
initial instruction of a function that followed such
|
|
|
|
alignment-introduced instructions.

|

maybe even VLIW-pack sequences of nop instructions as much as
|
|
|
|
possible for the selected machine type, just in case the alignment
|
|
|
|
code actually happens to run, but this is probably too much effort

for little gain. This code is not meant to be run anyway, so just

emit nops. */
