* compiler/blob: Add blob_skip_bytesJordan Justen2018-07-091-0/+6

* blob: Use intptr_t instead of ssize_tJason Ekstrand2017-10-131-3/+3
| | | | | | | | | | | ssize_t is a GNU extension and is not available on Windows or MacOS. Instead, we use intptr_t which should be effectively equivalent and is part of the C standard. This should fix the Windows and Mac OS builds.

* compiler/blob: Make some parameters void instead of uint8_tJason Ekstrand2017-10-121-2/+2
| | | | | | | | | There are certain advantages to using uint8_t internally such as well-defined arithmetic on all platforms. However, interfaces that work in terms of raw data should use a void* type. Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Jordan Justen <[email protected]>

* compiler/blob: Add (reserve|overwrite)_(uint32|intptr) helpersJason Ekstrand2017-10-121-2/+34
| | | | | | | | These helpers not only call blob_reserve_bytes but also make sure that the blob is properly aligned as if blob_write_* were called. Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
* compiler/blob: make blob_reserve_bytes() more usefulConnor Abbott2017-10-121-13/+5
| | | | | | | | | | | | | | | | Despite the name, it could only be used if you immediately wrote to the pointer. Noboby was using it outside of one test, so clearly this behavior wasn't that useful. Instead, make it return an offset into the data buffer so that the result isn't invalidated if you later write to the blob. In conjunction with blob_overwrite_bytes(), this will be useful for leaving a placeholder and then filling it in later, which we'll need to do for handling phi nodes when serializing NIR. v2 (Jason Ekstrand): - Detect overflow in the offset + to_write computation Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
* compiler/blob: Allow for fixed-size blobs with a NULL data pointerJason Ekstrand2017-10-121-0/+4
| | | | | | | | These can be used to easily count up the number of bytes that will be required by "writing" it into the NULL blob. Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Jordan Justen <[email protected]>

* compiler/blob: Switch to init/finish instead of create/destroyJason Ekstrand2017-10-121-8/+5
| | | | | | | | | There's no reason why that tiny bit of memory needs to be on the heap. We always put blob_reader on the stack, so why not do the same with the writable blob. Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
* compiler: Move blob up a levelJason Ekstrand2017-10-121-0/+307
We're going to want to use the blob for Vulkan pipeline caching so it makes sense to have it in libcompiler not libglsl. Reviewed-by: Nicolai Hähnle <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
