| | | | | | | | clobber with the 'y' constraint. Otherwise, we get the wrong return type and an assert, because it created a '<1 x i64>' vector type instead of the x86_mmx type. llvm-svn: 127185

* lib/CodeGen/TargetInfo.cpp: On Win64, arg i128 should be emitted as INDIRECT.NAKAMURA Takumi2011-02-221-2/+9
| | | | | | mingw-w64's i128 tweak should be done with x86_64-mingw32. llvm-svn: 126186

* lib/CodeGen/TargetInfo.cpp: Add Win64 calling conversion.NAKAMURA Takumi2011-01-171-2/+49
| | | | | | | FIXME: It would be incompatible to Microsoft's in one point. On mingw64-gcc, {i128} is expanded for args and returned as {rax, rdx}. llvm-svn: 123692
* Remove special handling for opaque Neon vector types.Bob Wilson2011-01-111-9/+0
| | | | | | Clang does not wrap the vectors in structs anymore so this isn't needed. llvm-svn: 123241
* Move DefaultABIInfo::classifyReturnType where it belongs. No functional change.Bob Wilson2011-01-101-15/+15

* 1. Add some ABI information for the Microblaze.Wesley Peck2010-12-191-0/+113

* Rename getBaseClassOffset to getBaseClassOffsetInBits and introduce a ↵Anders Carlsson2010-10-311-2/+2
| | | | | | getBaseClassOffset which returns the offset in CharUnits. Do the same thing for getVBaseClassOffset. llvm-svn: 117881
* Fix Whitespace.Michael J. Spencer2010-10-191-11/+11
| | | | llvm-svn: 116798
* We shouldn't keep track of MMX registers "needed" separately from the SSEBill Wendling2010-10-181-21/+11
| | | | | | registers needed. llvm-svn: 116772
* Reapply r116684 with fixes. The test cases needed to be updated.Bill Wendling2010-10-181-12/+47

* The "gcc.dg/compat/vector-1 -m32" test was broken after the MMX rewrite. TheBill Wendling2010-10-171-12/+47
| | | | | | | | function parameters weren't converted to use the correct type (x86_mmx). Add a check, similar to the one in llvm-gcc, to see if we need the x86_mmx type for that function parameter. If so, it coerces the type to be that. llvm-svn: 116684
* Per discussion with Sanjiv, remove the PIC16 target from mainline. When/ifChris Lattner2010-10-111-73/+0
| | | | | | | it comes back, it will be largely a rewrite, so keeping the old codebase in tree isn't helping anyone. llvm-svn: 116191
* IRgen/ABI/ARM: Return large vectors in memory.Daniel Dunbar2010-09-231-0/+4
| | | | llvm-svn: 114619
* IRgen/ABI/ARM: Trust the backend to pass vectors correctly for the given ABI.Daniel Dunbar2010-09-231-0/+11
| | | | | | | | | | - Therefore, we can lower out the NEON wrapper structs and pass the vectors directly. This makes a huge difference in the cleanliness of the IR after optimization. - I will trust, but verify, via future ABITest testing (for APCS-GNU, at least). llvm-svn: 114618
* IRgen/ABI/x86-32: Realign indirect arguments when the ABI requires us to passDaniel Dunbar2010-09-161-15/+24
| | | | | | them with a smaller alignment than the rest of codegen expects. llvm-svn: 114115
* IRgen/ABI: Add support for realigning structures which are passed by indirectDaniel Dunbar2010-09-161-1/+2
| | | | | | reference. llvm-svn: 114114
* IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types ↵Daniel Dunbar2010-09-161-3/+32
| | | | | | | | | | | get passed with a non-default-stack-ABI-alignment (of 16). - This fixes the ABI convenient, but breaks codegen since we now have underaligned arguments. Marginal improvement overall though, and will be fixed in next commit. llvm-svn: 114113
* IRgen/x86_32/Linux: Linux seems to align all stack objects to 4 bytes, unlikeDaniel Dunbar2010-09-161-3/+23
| | | | | | | Darwin. Checked vs the handiest Linux llvm-gcc I had around, someone on Linux is welcome to investigate more. llvm-svn: 114112
* fix rdar://8360877 a really nasty miscompilation in Boost.XpressiveChris Lattner2010-09-011-3/+47
| | | | | | | | | | | | | | | caused by my ABI work. Passing: struct outer { int x; struct epsilon_matcher {} e; int f; }; as {i32,i32} isn't safe, because the offset of the second element needs to be at 8 when it is interpreted as a memory value. llvm-svn: 112686
* same refactoring as before, this time on the argument side.Chris Lattner2010-09-011-16/+17
| | | | llvm-svn: 112684

* improve comments.Chris Lattner2010-08-261-5/+2

* fix 2xi16 to pass as i32 instead of <2 x i16>. The former passes inChris Lattner2010-08-261-0/+19
| | | | | | | memory (as required) the later now passes in an xmm register. This fixes gcc.dg/compat/vector_1 on x86-32. llvm-svn: 112211
* vector of long and ulong are also classified as INTEGER in x86-64 abi,Chris Lattner2010-08-261-1/+3
| | | | | | | this fixes rdar://8358475 a failure of the gcc.dg/compat/vector_1 abi test. llvm-svn: 112205
