Subject: radv: keep track of the disasm string in debug mode only
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=885d75760b9157f1d84105c979503ec8588470c6;p=mesa.git

radv: keep track of the disasm string in debug mode only

This will allow to dump the active shaders when a hang is
detected. Only the ASM will be dumped for now.
