<pre>In many cases assembler does show error position or indicates a position
incorrectly.
Examples:
// Incorrect error position, should point at '0x1FFFFF'
gfx9> s_atc_probe 0, s[4:5], 0x1FFFFF
_test.s:1:13: error: expected a 21-bit signed offset
s_atc_probe 0, s[4:5], 0x1FFFFF
^
// Error position is correct for gfx8 but incorrect for gfx9
gfx8> global_load_dword v1, v[3:4], off dlc
_test.s:3:35: error: invalid operand for instruction
global_load_dword v1, v[3:4], off dlc
^
gfx8> global_load_dword v1, v[3:4], off dlc
_test.s:3:38: error: failed parsing operand.
global_load_dword v1, v[3:4], off dlc
^
// Incorrect error position, should point at '3'
gfx8> ds_swizzle_b32 v8, v2 offset:swizzle(REVERSE,3)
_test.s:1:45: error: group size must be a power of two
ds_swizzle_b32 v8, v2 offset:swizzle(REVERSE,3)
^
// Incorrect error position, should point at '33'
gfx8> s_setreg_b32 hwreg(3,33,33), s2
_test.s:1:15: error: invalid bit offset: only 5-bit values are legal
s_setreg_b32 hwreg(3,33,33), s2
