From 42c7e752e1eae7663068e9c52ad77f7383d977e9 Mon Sep 17 00:00:00 2001 From: Robin Voetter Date: Sun, 31 Mar 2024 19:05:54 +0200 Subject: spirv: id range helper This allows us to more sanely allocate a continuous range of result-ids, and avoids a bunch of nasty casting code in a few places. Its currently not used very often, but will be useful in the future. --- src/codegen/spirv.zig | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/codegen/spirv.zig') diff --git a/src/codegen/spirv.zig b/src/codegen/spirv.zig index a47497d89d..f2b630b331 100644 --- a/src/codegen/spirv.zig +++ b/src/codegen/spirv.zig @@ -5440,7 +5440,7 @@ const DeclGen = struct { }; // First, pre-allocate the labels for the cases. - const first_case_label = self.spv.allocIds(num_cases); + const case_labels = self.spv.allocIds(num_cases); // We always need the default case - if zig has none, we will generate unreachable there. const default = self.spv.allocId(); @@ -5471,7 +5471,7 @@ const DeclGen = struct { const case_body = self.air.extra[case.end + items.len ..][0..case.data.body_len]; extra_index = case.end + case.data.items_len + case_body.len; - const label: IdRef = @enumFromInt(@intFromEnum(first_case_label) + case_i); + const label = case_labels.at(case_i); for (items) |item| { const value = (try self.air.value(item, mod)) orelse unreachable; @@ -5511,7 +5511,7 @@ const DeclGen = struct { const case_body: []const Air.Inst.Index = @ptrCast(self.air.extra[case.end + items.len ..][0..case.data.body_len]); extra_index = case.end + case.data.items_len + case_body.len; - const label: IdResult = @enumFromInt(@intFromEnum(first_case_label) + case_i); + const label = case_labels.at(case_i); try self.beginSpvBlock(label); -- cgit v1.2.3
