search for: unsized

Hi all, Attached is a simple patch that adds a more specific error when you have an unsized type in a gep. Turns $ echo "@g = global i64 ptrtoint(%C* getelementptr(%C* null, i32 1) to i64)" | opt -S opt: <stdin>:1:30: error: invalid indices for getelementptr @g = global i64 ptrtoint(%C* getelementptr(%C* null, i32 1) to i64) into $ echo "@g = global i64 ptrtoint(...

To reiterate what I said on IRC, I agree with David and would expect the verifier to reject unsized loads and stores.

This came up in D20764, this IR verifies today: %X = type opaque define void @f_0(%X* %ptr) { %t = load %X, %X* %ptr ret void } define void @f_1(%X %val, %X* %ptr) { store %X %val, %X* %ptr ret void } which I found surprising -- what does it mean to load / store values of unknown sizes? Passing it to llc fails an assertion. Are there legitimate cases where we'd want to generate

...able (AllocaInst). Later on I intend to indirectly branch to this address by "dereferencing" the variable. Is this possible? I tried creating an instance of AllocaInst but I'm not quite sure which type to use. Using block->getType() results in a segmentation fault (Cannot allocate unsized type %myVar = alloca label). Code might help: AllocaInst *myVar = new AllocaInst(blockToStore.getType(), "myVar", curBlock); new StoreInst(&blockToStore, myVar); I guess I should use an integer type to store the address but then LLVM complains about type mismatch as I don not know...

Hi folks, We seem to be converging on how the representation of scalable vectors will be implemented in IR, and we also have support for such vectors in the AArch64 back-end. We're also fresh out of the release process and have a good number of months to hash out potential problems until next release. What are the next steps to get this merged into trunk? Given this is a major change to IR,

Hi all. Recently I was looking for an IMAP-server with Oracle support and unfortunatelly I couldn't find one. It was a surprise for me but there is no such functionality at all. So I've chosen an IMAP-server with most flexible and convinient architecture that was Dovecot-1.2.9 and written a driver for Oracle RDBMS support. I used Oracle Pro*C so a Pro*C preprocessor is needed to

Hi David, Sorry to bother you, but I would like to get some suggestions on your recent work of token type. I’m currently working on changing gc.statepoint to return a token type instead of a i32 type. The reason is that with the current implementation, gc.statepoint could potentially be fed into PHI nodes, and break RewriteStatepointsForGC pass later. Using token type would help us to avoid

...e to the opposite conclusion. While in theory the intrinsics and opaque types are more targeted and confined, this only remains true *if* we don't end up teaching a bunch of transformations and analysis passes about them. However, I feel it is inevitable that we will:  1. While we already have unsized types in the IR, SV will add more of them, and opaque or otherwise, there will be some cost to making all of the relevant places in the optimizer not crash in their presence. This cost we end up paying either way.  2. We're going to end up wanting to optimize SV operations. If we have intrinsi...

...unsigned integer that represents the size_t type is no longer known. The C spec states in section 6.5.3.4.4 that "The value of the result is implementation-defined, and its type(an unsigned integer type) is size_t, defined in <stddef.h> (and other headers)." SPIR defines size_t as a unsized unsigned integer and as such cannot be known until the SPIR binary is lowered to the device. At that time, SPIR is known and as such can be lowered correctly to its type. *** Hal Finkel: Handling FP_CONTRACT *** *****Comment: The current specification provides a mechanism for handling FP...
