Hi @ll, targetting i386, LLVM/clang generates wrong code for the following functions: unsigned long __bswapsi2 (unsigned long ul) { return (((ul) & 0xff000000ul) >> 3 * 8) | (((ul) & 0x00ff0000ul) >> 8) | (((ul) & 0x0000ff00ul) << 8) | (((ul) & 0x000000fful) << 3 * 8); } unsigned long long __bswapdi2(unsigned long

Hi, I've some troubles setting up the dict based quota plugin for mdbox, it always returns a error when lmtp tries to deliver an e-mail: Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre at ull.es): Error: fstat(/sharedfs/10.4.1.107/ull.es/54/asmarre/dovecot-quota.lock) failed: No such file or directory Apr 8 12:40:16 mb07 dovecot: lmtp(3001, asmarre at ull.es): Error: file dict commit:

bswapdi2 for i386 is correct Bits 31:0 of the source are loaded into edx. Bits 63:32 are loaded into eax. Those are each bswapped. The ABI for the return is edx contains bits [63:32] and eax contains [31:0]. This is opposite of how the register were loaded. ~Craig On Sun, Nov 25, 2018 at 10:36 AM Craig Topper <craig.topper at gmail.com> wrote: > bswapsi2 on the x86-64 isn't using

share/compat.h contains the following code: /* adjust for compilers that can't understand using LLU suffix for uint64_t literals */ #ifdef _MSC_VER #define FLAC__U64L(x) x #else #define FLAC__U64L(x) x##LLU #endif I tested MSVS 2005 and indeed it doesn't support LLU suffix, but it can compile a code with ULL suffix. Also, http://gcc.gnu.org/onlinedocs/gcc/Long-Long.html mentions ?ULL?

I was able to get the loop to increment from -999 to 0 using IR directly. That got rid of the cmpq. The carry i was after was able to be obtained using the intrinsic @llvm.uadd.with.overflow.i64, however there is no way to add with carry and have it realise that the resulting *carry out* cannot exceed 1. It actually writes the carry to a byte, and then uses logical operations on it, which slows

I just compiled the two attached files in 32-bit mode and ran it. It printed efcdab8967452301. I verified via objdump that the my_bswap function contains the follow assembly which I believe matches the assembly you linked to on godbolt. _my_bswap: 1f70: 55 pushl %ebp 1f71: 89 e5 movl %esp, %ebp 1f73: 8b 55 08 movl 8(%ebp), %edx 1f76: 8b 45 0c movl 12(%ebp), %eax 1f79: 0f c8

Hi Bill- I think, ideally, the backend would be able to match arbitrary-precision arithmetic to add-with-carry or subtract-with-borrow through i65/i33. That would remove the need for the overflow intrinsics entirely. Alistair On 13 Jun 2010, at 02:27, Bill Hart wrote: > I was able to get the loop to increment from -999 to 0 using IR > directly.

Hi All, I've been building and testing FLAC and have run a problem. I get a number of 'integer constant out of range' warnings during the make, and these give rise to failures in the test suite: testing zeroes, raw_uint32*... FAILED pattern match testing process_until_end_of_stream()... 0... 1... 2... ERROR: metadata block mismatch for example. The problem is that gcc

Yeah I had a think about it, and I think intrinsics are the wrong way to do it. So I'd say you are likely right. Bill.

Hi, samba 2.2.8a freshly compiled cups 1.1.19final-1 (debian) while using cupsaddsmb, all runs well until adddriver, when rpcclient returns a cryptic NT_STATUS_NO_SUCH_DEVICE. I've followed the SambaPrintHowto 3.0 from 7.11.6.1 to 7.11.6.6, and it fails on the latest as well. Here is some more information. ===8<=== cupsaddsmb -a -v Running command: smbclient //localhost/print\$ -N

In DataTypes.h starting on line 121 are these lines: #define INT8_C(C) C #define UINT8_C(C) C #define INT16_C(C) C #define UINT16_C(C) C #define INT32_C(C) C #define UINT32_C(C) C ## U #define INT64_C(C) ((int64_t) C ## LL) #define UINT64_C(C) ((uint64_t) C ## ULL) They are conflicting with the cstdint when we have updated headers in our MSVC build. I could have sworn I talked about this

Hello, Apologies if this question has already arised, hope you can help me to the find the solution to this or point the place to look at. I have a multidimensional piece-wise regression linear problem, i.e. to find not only the regression coefficients for each "interval" but also the beginning and ends of the intervals. To simplify it to the one dimensional case and two intervals,
