-- v3: vkd3d-shader/hlsl: Free the "iter" block pointer on success in create_loop(). vkd3d-shader/hlsl: Return a hlsl_block from the "expr_statement" and "expr" rules. vkd3d-shader/hlsl: Return a hlsl_block from the "jump_statement" rule. vkd3d-shader/hlsl: Return a hlsl_block from the "selection_statement" rule. vkd3d-shader/hlsl: Return a hlsl_block from the "loop_statement" rule. vkd3d-shader/hlsl: Return a hlsl_block from the "statement" rule.
From: Zebediah Figura zfigura@codeweavers.com
As well as from the "statement_list" and "compound_statement" rules, which trivially pass through from "statement". --- libs/vkd3d-shader/hlsl.y | 63 +++++++++++++++++++++++----------------- 1 file changed, 37 insertions(+), 26 deletions(-)
