I'm working on lldb. I've just submitted a very small change (r217229) to Triple.h/.cpp. Soon after I get a mail subject: buildbot failure in LLVM on lld-x86_64-darwin13 Details: http://lab.llvm.org:8011/builders/lld-x86_64-darwin13/builds/2571 Blamelist: mg11 My small change certainly did not cause lldb's build to fail on my machine. I looked into the build-log: http://lab.llvm.org:8011/builders/lld-x86_64-darwin13/builds/2571/steps/build_Lld/logs/stdio It wasn't obvious how my change resulted in failure. When I tried to replicate the build of the last 2 targets listed in the log, I did see this, on my machine: $ ninja LLVMCodeGen [15/15] Linking CXX shared library lib/libLLVMCodeGen.so $ ninja LLVMMipsCodeGen ninja: error: unknown target 'LLVMMipsCodeGen' Can anyone help? thanks Matt Member of the CSR plc group of companies.

Hi Matthew,> My small change certainly did not cause lldb's build to fail on my machine. > I looked into the build-log:It's probably just lld building with -Werror (and likely on a different compiler than you too, or you'd have seen the warning). I've fixed this one up in r217233, we'll see what that does to the lld builder.> When I tried to replicate the build of the last 2 targets listed in the log, > I did see this, on my machine:That's usually not particularly useful even if there are targets for them. The builds are very parallel and it's difficult to work out just which target actually caused the problem "ninja check-all" should be fine for most cases. Cheers. Tim.
Hi,
The build log show this error:
/Users/buildslave/as-bldslv9/lld-x86_64-darwin13/llvm.src/lib/Target/ARM/MCTargetDesc/ARMMCTargetDesc.cpp:92:11:
error: enumeration values 'KalimbaSubArch_v3',
'KalimbaSubArch_v4', and 'KalimbaSubArch_v5' not handled in
switch [-Werror,-Wswitch]
switch (triple.getSubArch()) {
This is a warning turned into an error by -Werror. LLVM’s code should be warning
free.
You indeed added these entries to the enum and they seem not to be handled in
ARMMCTargetDesc.cpp. If you don’t know how to add these to ParseARMTriple(), I’d
suggest you revert your change until someone with ARM MC knowledge helps you
out.

Hi Tim, Thanks for helping me with this. The route which I take to build lldb (cmake/ninja on Fedora) seems (irritating) permissive of warnings. So I missed this when I originally submitted my change. I'll certainly bear this in mind if I make any more llvm changes! thanks Matt Tim Northover wrote:> Hi Matthew, > >> My small change certainly did not cause lldb's build to fail on my machine. >> I looked into the build-log: > It's probably just lld building with -Werror (and likely on a > different compiler than you too, or you'd have seen the warning).

Hi Fred,
Thanks. How did you get to
"
The build log show this error:
/Users/buildslave/as-bldslv9/lld-x86_64-darwin13/llvm.src/lib/Target/ARM/MCTargetDesc/ARMMCTargetDesc.cpp:92:11:
error: enumeration values 'KalimbaSubArch_v3',
'KalimbaSubArch_v4', and 'KalimbaSubArch_v5' not handled in
switch [-Werror,-Wswitch]
switch (triple.getSubArch()) {
"
from here
http://lab.llvm.org:8011/builders/lld-x86_64-darwin13/builds/2571
Sorry to seem lame, but I could have fixed it myself if I'd known how to
navigate to that line describing the failed invocation.
thanks
Matt
