search for: setglobals

Emitting calls to these functions (written in an .ll file linked in) works fine, and does the right thing. %Any = type { i8*, i32 } define dllexport void @setGlobal(%Any* %ptr, %Any %value) { store %Any %value, %Any* %ptr ret void } define dllexport %Any @getGlobal(%Any* %ptr) { %val = load %Any, %Any* %ptr ret %Any %val } Trying to replace the setGlobal call with what should be

Since the getelementptrs were implicitly generated by the CreateStore/Load I'm not sure how to get access to them. So I hacked the assignment to be done thrice: once using a manual decomposition into two GEPs and stores, once using the "big" CreateStore, once via the setGlobal function, printing addresses and memory contents at each point to the degree that I have access to them.

That's useful to know that the static compilation code path works. Furthermore, as expected from that: 52: c7 05 04 00 00 00 d5 00 00 00 movl $213, 4 00000054: IMAGE_REL_I386_DIR32 _foo It looks like the offset `4` of the second field of your struct is correct in the object file, so this does seem to be a problem in the JIT-specific linking/loading.

My code was hinky, but only in the sense that I was accidentally duplicating the definition variable in the module where the function was. With only the declaration in the second module loading the bitcode reproduces the issue. Managed an lli reproduction: $ cat jit-0.ll target datalayout = "e-m:x-p:32:32-i64:64-f80:32-n8:16:32-a:0:32-S32" target triple =

Hi, this series adds a couple bits more in v2v to convert Debian/Ubuntu (and derived) guests. The series does not complete the support (see known issues below), but all the patches here should be fit for review and inclusion. The series does not enable the conversion, yet. Known issues: * currently tested with simple local guest images, hence needs testing with real guests on

The following series of patches adds support for converting SUSE guests through virt-v2v. These changes should not impact non-SUSE guest conversions.

This is a new conversion module to convert SUSE Linux and openSUSE guests. The converter is based on the RedHat module, and should offer the same functionality on both SUSE and RedHat hosts. There are a few additional messages in this module, such as reporting of packages when installing through zypper or the local virt-v2v repo. These messages don't necessarily flow unless verbose switches
