...sh, or miscompile when encountering such a modified GEP. I think it is unfeasible to change all code to properly handle the new form at once. 2. Johannes' interpretation is to add some kind of metadata to GEPs, in addition to the naive computation, such as: %offset1= mul i64. %i, %n %offset2 = add i64, %j, %offset1 %1 = getelementptr double, double* %A, inrange i64 %offset2 [ "multi-dim"(i64 %n) ] This was not obvious to me. The code above uses operand bundle syntax. During our discussing for this RFC we briefly discussed metadata, which unfortunately do not allow refere...

v1 was here: https://www.redhat.com/archives/libguestfs/2019-January/thread.html#00198 For v2 I changed most existing prerequisite tests to use the new mechanism. I only changed simple tests. There are a few more complex tests that don't fit the “requires model” and those are not changed. I normalized qemu-io/qemu-img testing to always use the --version flag, where previously we used a mix

Combine much common code into tests/functions.sh. Patch 1: Preparation for patch 3. Patch 2: Fix a long-standing bug in how man pages links are generated. Patch 3: Common code for iterating a test function over every plugin. Patch 4: Common code for starting nbdkit in a test and waiting for the PID file to appear. This is the largest and most complex of the patches but is

Adding an intrinsic is easier than adding or extending an existing instruction, as suggested by

Dear List, I'm trying to get diff/removed data and it's offset out. So I write a functions in receive_data. When I run backup, I found there is a weird behavior which I don't understand. i = recv_token(f_in, &data) will receive (i = -1, offset2 = 0) some where in the middle of the transfer procedure. That's to say, it's going to transfer the first data block from sender, but I have been transferring almost half of the file. I noticed it was 92nd block (sum.blength = 700) . Hope I have a clear explanation. I'm really confused...
