| | | | | | | | | | | declarations. These are the fixes that I was pretty confident about, there are still a lot of other llvm-gcc warnings of which I'm not sure if they can be safely ignored or fixed, without breaking the test case. This fixes 11 testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52176 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | don't fail when (expected) error output is produced. This fixes 17 tests. While I was there, I also made all RUN lines of the form "not llvm-as..." a bit more consistent, they now all redirect stderr and stdout to /dev/null and use input redirect to read their input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52174 91177308-0d34-0410-b5e6-96231b3b80d8

* Change llvm.exp so it no longer ignores some errors when executing dejagnuMatthijs Kooijman2008-06-101-0/+4
| | | | | | | | | | | | | | | | | | | | | | tests. This breaks 80 tests in the tree. The interesting part here is that this no longer ignores syntax errors in RUN command lines. Some tests have not been working all the time because of this. The tricky part is that it now also views any stderr output as an error. This can be suppressed in tcl 8.5, but let's not add this dependency. Instead, all testcases should be changed to redirect stderr if they expect stderr output. This holds in particular for lines like: ; RUN: not llvm-as < %s where an error is expected (but I think I can solve this by modifying the not script). Also, compilations resulting in warnings will now also fail (so the warnings should be fixed, disabled or redirected...). I'll continue with fixing the testcases that are broken now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52172 91177308-0d34-0410-b5e6-96231b3b80d8

* Change packed struct layout so that field sizesDuncan Sands2008-06-041-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are the same as in unpacked structs, only field positions differ. This only matters for structs containing x86 long double or an apint; it may cause backwards compatibility problems if someone has bitcode containing a packed struct with a field of one of those types. The issue is that only 10 bytes are needed to hold an x86 long double: the store size is 10 bytes, but the ABI size is 12 or 16 bytes (linux/ darwin) which comes from rounding the store size up by the alignment. Because it seemed silly not to pack an x86 long double into 10 bytes in a packed struct, this is what was done. I now think this was a mistake. Reserving the ABI size for an x86 long double field even in a packed struct makes things more uniform: the ABI size is now always used when reserving space for a type. This means that developers are less likely to make mistakes. It also makes life easier for the CBE which otherwise could not represent all LLVM packed structs (PR2402). Front-end people might need to adjust the way they create LLVM structs - see following change to llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51928 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement CBE support for first-class structs and array values,Dan Gohman2008-06-021-1/+1
| | | | | | | | | | | | | | | | and insertvalue and extractvalue instructions. First-class array values are not trivial because C doesn't support them. The approach I took here is to wrap all arrays in structs. Feedback is welcome. The 2007-01-15-NamedArrayType.ll test needed to be modified because it has a "not grep" for a string that now exists, because array types now have associated struct types, and those struct types have names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51881 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix the position of MemOperands in nodes that use variadic_opsDan Gohman2008-06-021-0/+11

This bug was recently uncovered by the addition of patterns for CALL32m and CALL64m, which are nodes that now have both MemOperands and variadic_ops. This bug was especially visible with PIC in various configurations, because the new patterns are matching the indirect call code used in many PIC configurations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51877 91177308-0d34-0410-b5e6-96231b3b80d8

Only allow changing between pointer types, and between pointer types and integers of the same size. For return values ptr -> intptr was already allowed; I added ptr -> ptr and intptr -> ptr while there. As shown by a recent objc testcase, changing the way parameters/return values are passed can be fatal when calling code written in assembler that directly manipulates call arguments and return values unless the transform has no impact on the way they are passed at the codegen level. While it is possible to imagine an ABI that treats integers of pointer size differently to pointers, I don't think LLVM supports any so the transform should now be safe while still being useful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51834 91177308-0d34-0410-b5e6-96231b3b80d8
