[PATCH vkd3d] vkd3d-shader/hlsl: Add support for texture arrays. Replace sampler_dim with resource_dim.
by Francisco Casas Dec. 7, 2021

Dec. 7, 2021

New values for enum hlsl_sampler_dim are added in order to represent dimension types for textures that don't have their analog sampler, like Texture2DArray. enum hlsl_sampler_dim is then renamed to enum hlsl_resource_dim to convey that it no longer represents just sampler types. Parsing and initialization of Texture2DArray, Texture2DMS, Texture2DMSArray, and TextureCubeArray is added. sampler_dim_count() is moved from hlsl.y to hlsl.h since it can be useful in other files, like in write_sm4_ld() in hlsl_sm4.c. --- This patch is an alternative to 221390, which proposed to separate sampler_dim into sampler_dim and texture_dim. It will probably be resent after Matteo's batch is reviewed.

[RFC PATCH v3 5/5] ntdll: Properly parse UDF instruction in ARM.
by Jinoh Kang Dec. 7, 2021

Dec. 7, 2021

Today, the UDF instruction handler code assumes Thumb mode code, and cannot recognise the UDF.W form or equivalent instructions in ARM mode encoding. Fix this by generalising the UDF instruction parser code.

[PATCH v3 00/17] WineDbg enhance set/get operations on integers & floats
by Eric Pouech Dec. 7, 2021

Dec. 7, 2021

With this series: - all expression computations inside WineDbg are done with largest available integer (64bit currently) - improved reading / writing integers (esp. on bit fields or different sizes) - implemented writing floats & doubles (including conversion when needed) - improved detection of incompatible types in assigment - code simplification (removed methods for managing floats and integers) v2 -> v3: - renamed where bit field in struct dbg_lvalue into in_debuggee (and removed associated helper) - removed unused dbg_print_udecimal v1 -> v2: - no change to basic types (esp. long) (new internal type int64 has been added) - removed console related patch (some more testing required) there will be another serie after this one that will better integrate debuggee's generated types (but requires a bit of reworking in WineDbg parser that would be too large here) A+ --- Eric Pouech (17): programs/winedbg: don't pretend all dbg_internal_var instances will hold DWORD_PTR programs/winedbg: let savable variables' size be a DWORD programs/winedbg: set pid and tid internal variables' type to be a DWORD programs/winedbg: introduce dbg_lg(u)int_t and migrate all integral computations on this type programs/winedbg: remove methods for fetching/storing integers in CPU backends programs/winedbg: renamed extract_longlong() into extract_lgint() for clarity programs/winedbg: split print_longlong into print_(s|u)decimal (to mimic print_hex) programs/winedbg: revamp dbg_lvalue structure and add helpers for init programs/winedbg: add bitfield capability to dbg_lvalue programs/winedbg: move bitfield extraction to extract_lgint dbghelp: in SymGetTypeInfo(), return the correct basetype for enums programs/winedbg: add helper to compare types and use it to detect wrong assigments programs/winedbg: add helper to transfer memory between lvalues programs/winedbg: correctly store integers into a bitfield programs/winedbg: remove fetch_float() method from CPU backends programs/winedbg: implement proper assignements of floating point numbers programs/winedbg: don't hard code sizes dlls/dbghelp/type.c | 3 +- programs/winedbg/be_arm.c | 82 +++-------- programs/winedbg/be_arm64.c | 118 +++++---------- programs/winedbg/be_cpu.h | 7 - programs/winedbg/be_i386.c | 150 +++++++------------ programs/winedbg/be_x86_64.c | 196 ++++++++++--------------- programs/winedbg/break.c | 4 +- programs/winedbg/dbg.y | 6 +- programs/winedbg/debug.l | 8 +- programs/winedbg/debugger.h | 75 +++++++--- programs/winedbg/expr.c | 82 ++++------- programs/winedbg/memory.c | 192 ++++++++++++++++++++---- programs/winedbg/stack.c | 6 +- programs/winedbg/symbol.c | 21 +-- programs/winedbg/tgt_active.c | 6 +- programs/winedbg/types.c | 268 ++++++++++++++++++++++++++-------- programs/winedbg/winedbg.c | 14 +- 17 files changed, 663 insertions(+), 575 deletions(-)
