Method While

core/codegen/builder.go:198–215

While builds a logic block with the following psuedocode: while test() { loop() }

(test func() *Value, loop func())

// }
//
func (b *Builder) While(test func() *Value, loop func()) {
	testBlock := b.m.ctx.AddBasicBlock(b.function.llvm, "while_test")
	loopBlock := b.m.ctx.AddBasicBlock(b.function.llvm, "while_loop")
	exitBlock := b.m.ctx.AddBasicBlock(b.function.llvm, "while_exit")

	b.llvm.CreateBr(testBlock)

	b.block(testBlock, llvm.BasicBlock{}, func() {
		cond := test()
		if !b.IsBlockTerminated() {
			b.llvm.CreateCondBr(cond.llvm, loopBlock, exitBlock)
		}
	})

	b.block(loopBlock, testBlock, loop)

	b.setInsertPointAtEnd(exitBlock)
}
