Subject: gallium: remove dependencies on pipe_shader_state's semantic info
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cddeca51adf0d2b736a223e47b60f6ef3be85bff;p=mesa.git

gallium: remove dependencies on pipe_shader_state's semantic info

Use tgsi_scan_shader() to populate a tgsi_shader_info struct and use that instead.
