Enables users to specify the target section name when scanning a PE file for a pattern.
This provides more flexibility in locating patterns within a PE file, as it's not limited to the ".text" section.
Adjusts the virtual method calling convention based on the compiler (_MSC_VER).
This ensures compatibility and correct behavior on different platforms.
Updates the PE scanner implementation to support both 32-bit and 64-bit architectures.
Leverages `std::variant` and a generic `ImageNtHeaders` to abstract architecture-specific details.
Simplifies the logic for retrieving section data, generalizing the process for improved maintainability.
Initializes infrastructure for PE file scanning.
Adds data structures for PE headers (DOS, optional, section),
including user-defined types for section characteristics.
Refactors existing pattern scanning code to utilize new PE data structures.
Adds basic parsing of PE headers.
Defines `DosHeader` and `FileHeader` structures to represent PE file header information.
Includes definitions for `MachineId` enum and `FileCharacteristics` union.
These definitions are prerequisite for PE file parsing and analysis.
Adds functionality to extract a specific section from a PE file and scan for a given pattern within that section.
Introduces `extract_section_from_pe_file` to isolate a section, enabling more targeted pattern searches.
Overhauls `scan_for_pattern_in_file` to utilize extracted section data and improve accuracy.
Implements a pattern scanning feature that allows searching for byte patterns within a byte range.
Adds `scan_for_pattern` method to `PatternScanner` to locate a pattern within a byte span.
Adds corner case tests to verify functionality and handle invalid inputs.
Adds new test cases to cover additional scenarios for pattern scanning, including tests for leading/trailing whitespace and spacing variations to ensure robustness.
Implements a pattern scanner for byte sequence parsing.
Introduces `omath::PatternScanner` to parse pattern strings, which represent byte sequences.
Adds support for wildcard characters ('?' and '?') to represent optional bytes in the pattern.
Includes unit tests for basic read operations to ensure proper functionality.
Removes preprocessor check for FMA instructions in matrix multiplication functions.
This simplifies the code and relies on the compiler's ability to optimize the
code based on available hardware support. The assumption is that modern
compilers will automatically utilize FMA instructions if available, and fall
back to alternative implementations if not.
Ensures that AVX2 intrinsics are only included when the
OMATH_USE_AVX2 preprocessor definition is set. This prevents
compilation errors when AVX2 support is not available or
explicitly disabled.
The C standard library function fmodf is not guaranteed to be in namespace std, and in fact is not with a default Ubuntu 24.04 installation, leading to the following compile error:

Only the 'sufficient additional overloads' of `fmod` are guaranteed to be in `std`. Since this is clearly intended to call the (float, float) overload, explicitly cast `((green - blue) / delta)` (which is a `double`) to `float` and call the name in `std` as suggested by the diagnostic.
Optimizes matrix multiplication by specializing the algorithm
based on the matrix storage type (row-major or column-major).
This change significantly improves performance by leveraging
memory access patterns specific to each storage order.
