The LLVM cmake documentation implies that debug should have enabled asserts, that is it says that:</div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><br></div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">"<strong style="font-family: 'Lucida Grande', 'Lucida Sans Unicode', Geneva, Verdana, sans-serif; font-size: 14px; line-height: 21px;">LLVM_ENABLE_ASSERTIONS</strong><span style="background-color: rgb(255, 255, 255); font-family: 'Lucida Grande', 'Lucida Sans Unicode', Geneva, Verdana, sans-serif; font-size: 14px; line-height: 21px;">:BOOL</span><dd style="margin-top: 3px; margin-bottom: 10px; margin-left: 30px; font-family: 'Lucida Grande', 'Lucida Sans Unicode', Geneva, Verdana, sans-serif; font-size: 14px; line-height: 21px; background-color: rgb(255, 255, 255); position: static; z-index: auto;">Enables code assertions.
