Disassembler was called with non-default params, loosing FRIENDLY_NAMES.
This commit changes the call options to allow the spirv-opt to show
friendly names instead of raw-ids. Might be more helpful when reading
the SPIRV-opt output.
Fixes#4882

* PassManager: Print errors occurring during disassembly
Otherwise one could be greeted by the following text when running
spirv-opt withe the `--print-all` flag:
; IR before pass wrap-opkill
; IR before pass eliminate-dead-branches
; IR before pass merge-return
With this commit, one will instead get:
error: line 143: Invalid opcode: 400
warning: line 0: Disassembly failed before pass wrap-opkill
error: line 143: Invalid opcode: 400
warning: line 0: Disassembly failed before pass eliminate-dead-branches
error: line 143: Invalid opcode: 400
warning: line 0: Disassembly failed before pass merge-return
* PassManager: Use the right target environment when disassembling
Disassembly would fail if features from a newer version of SPIR-V than
1.2 were used.
This CL moves the files in opt/ to consistenly be under the opt::
namespace. This frees up the ir:: namespace so it can be used to make a
shared ir represenation.
This patch adds a new option --time-report to spirv-opt. For each pass
executed by spirv-opt, the flag prints resource utilization for the pass
(CPU time, wall time, RSS and page faults)
This fixes issue #1378
Adds optimizer API to write disassembly to a given output stream
before each pass, and after the last pass.
Adds spirv-opt --print-all option to write disassembly to stderr
before each pass, and after the last pass.
This patch adds a new constant manager class to interface with
analysis::Constant. The new constant manager lives in ir::IRContext
together with the type manager (analysis::TypeManager).
The new analysis::ConstantManager is used by the spec constant folder
and the constant propagator (in progress).
Another cleanup introduced by this patch removes the ID management from
the fold spec constant pass, and ir::IRContext and moves it to
ir::Module. SSA IDs were maintained by IRContext and Module. That's
pointless and leads to mismatch IDs. Fixed by moving all the bookkeeping
to ir::Module.
This change will move the instances of the def-use manager to the
IRContext. This allows it to persists across optimization, and does
not have to be rebuilt multiple times.
Added test to ensure that the IRContext is validating and invalidating
the analyses correctly.
This is the first part of adding the IRContext. This class is meant to
hold the extra data that is build on top of the module that it
owns.
The first part will simply create the IRContext class and get it passed
to the passes in place of the module. For now it does not have any
functionality of its own, but it acts more as a wrapper for the module.
The functions that I added to the IRContext are those that either
traverse the headers or add to them. I did this because we may decide
to have other ways of dealing with these sections (for example adding a
type pool, or use the decoration manager).
I also added the function that add to the header because the IRContext
needs to know when an instruction is added to update other data
structures appropriately.
Note that there is still lots of work that needs to be done. There are
still many places that change the module, and do not inform the context.
That will be the next step.
Add extra iterators for ir::Module's sections
Add extra getters to ir::Function
Add a const version of BasicBlock::GetLabelInst()
Use the max of all inputs' version as version
Split debug in debug1 and debug2
- Debug1 instructions have to be placed before debug2 instructions.
Error out if different addressing or memory models are found
Exit early if no binaries were given
Error out if entry points are redeclared
Implement copy ctors for Function and BasicBlock
- Visual Studio ends up generating copy constructors that call deleted
functions while compiling the linker code, while GCC and clang do not.
So explicitly write those functions to avoid Visual Studio messing up.
Move removing duplicate capabilities to its own pass
Add functions running on all IDs present in an instruction
Remove duplicate SpvOpExtInstImport
Give default options value for link functions
Remove linkage capability if not making a library
Check types before allowing to link
Detect if two types/variables/functions have different decorations
Remove decorations of imported variables/functions and their types
Add a DecorationManager
Add a method for removing all decorations of id
Add methods for removing operands from instructions
Error out if one of the modules has a non-zero schema
Update README.md to talk about the linker
Do not freak out if an imported built-in variable has no export
