There's two pieces of this that are handy. First, checking the normal integrated-assembler code path. That doesn't check the actual assembler, but rather the binary encoder and object file emitter. To test that, I did runs with a locally modified clang that enabled the integrated assembler by default for my target (ARM/Darwin at the time). The second piece is checking the assembler itself. For that, I ran the full test suite and kept the .s files around. Then I ran each .s file through plain 'as' and llvm-mc and did a binary comparison of the results. Anything that showed up, I analyzed to see if it was innocuous or an error.</div><div><br></div><div>-Jim</div><div><br></div><div>On Oct 15, 2012, at 2:22 PM, "Carter, Jack" <<a href="mailto:jcarter@mips.com" target="_blank">jcarter@mips.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; "><div style="direction: ltr; font-family: Tahoma; font-size: 10pt; ">Has anyone converted llvm/projects/test-suite to use the llvm assembler instead of gcc?<br></div></div></blockquote><div><br></div><blockquote type="cite"><div style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; "><div style="direction: ltr; font-family: Tahoma; font-size: 10pt; ">If so, what was needed to change and how?<br><br>My assumption is that this would be a good way to test the llvm assembler.<br><br>Jack<br></div>_______________________________________________<br>LLVM Developers mailing list<br><a href="mailto:LLVMdev@cs.uiuc.edu" target="_blank">LLVMdev@cs.uiuc.edu</a><span class="Apple-converted-space"> </span> <a href="http://llvm.cs.uiuc.edu" target="_blank">http://llvm.cs.uiuc.edu</a><br><a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev" target="_blank">http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev</a></div></blockquote></div></div></div></div></blockquote></div><br></body></html>
