Most OSes provide binary compatibility, in each version of the OS, for most binaries built to run on earlier versions of the OS. For example, many executables compiled for Windows 3.1 , Windows 95 or Windows 2000 can also be run on Windows XP or Windows 7 , and many applications for DOS ran on much newer versions of Windows up to Windows 10 for ...
Tombstone diagram representing an Ada compiler written in C that produces machine code. Representation of the process of bootstrapping a C compiler written in C, by compiling it using another compiler written in machine code. To explain, the lefthand T is a C compiler written in C that produces machine code.
A high-level comparison of in-kernel and kernel-to-userspace APIs and ABIs The Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI. Keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is an interface between two binary program ...
Bootstrappable builds, a process of compiling software that doesn't depend on (compiler) binaries that aren't built from source by this process. [1] [2] [3]This process can protect against compiler backdoors: if the build process doesn't depend on binary code that is difficult to audit, then a compiler backdoor cannot be hidden in compiler binaries anymore.
Source code compiled using deterministic compilation will always output the same binary. [1] [2] [3] Reproducible builds can act as part of a chain of trust; [1] the source code can be signed, and deterministic compilation can prove that the binary was compiled from trusted source code. Verified reproducible builds provide a strong ...
A binary recompiler is a compiler that takes executable binary files as input, analyzes their structure, applies transformations and optimizations, and outputs new optimized executable binaries. [ 1 ]
A binary optimizer takes the existing output from a compiler and produces a better execution file with the same functionality. An object code optimizer , sometimes also known as a post pass optimizer or, for small sections of code, peephole optimizer , forms part of a software compiler .
The minimum information contained in a symbol table used by a translator and intermediate representation (IR) includes the symbol's name and its location or address. For a compiler targeting a platform with a concept of relocatability, it will also contain relocatability attributes (absolute, relocatable, etc.) and needed relocation information for relocatable symbols.
