There are over 50 compilers for C like ICC by Intel to GNU GCC by GNU Project. The focus of having multiple compilers is to optimize the compiled C code for specific hardware and software environments. This has lead to a vast number of compilers but some have been abandoned in the path.
Some compilers were developed in 1970s (PCCM by Bell Labs) while the recent ones are from 2017 (AOCC by AMD).
Some compilers like LabWindows are used by a specific and small group of developers. At the same time, there are compilers like GNU GCC and ICC that are widely used till date.
Following is the ultimate list of C compilers that found some users:
Compiler | Release | Developer | In Wide Use | Users |
---|---|---|---|---|
pccm | 1973 | Bell Labs | No | General |
BSD C | 1979 | Zolman | No | BSD Unix |
Aztec C | 1980 | Manx Software Systems | No | DOS |
ACK | 1980 | Tanenbaum, Jacobs | Yes | NetBSD |
Lattice C | 1982 | Steve Krueger | No | DOS |
MPW | 1986 | Apple | No | Early Mac |
GCC | 1987 | GNU Project | Yes | General |
Turbo C | 1987 | Turbo | No | Turbo IDE |
Megamax C | 1988 | Megamax, Inc | No | Atari + Mac |
Acorn C | 1988 | Acorn | Yes | RISC OS |
LabWindows | 1989 | National Instruments | Yes | NIC |
QuickC | 1990 | Microsoft | No | DOS |
Oracle C | 1991 | Oracle | Yes | Oracle Developer Studio |
MinGW | 1993 | Peters | Yes | Windows |
MSVC | 1993 | Microsoft | Yes | Visual IDE |
CodeWarrior | 1993 | Metrowerks | No | Motorola 68K |
LCC | 1994 | Dave Hanson, Chris Fraser | No | MathWorks |
cc65 | 1999 | Bassewitz | Yes | Old 6502 systems |
Open64 | 2002 | Open64 dev | Yes | Itanium, x86-64 |
ICC | 2003 | Intel | Yes | Intel Systems |
Watcom C | 2003 | Watcom | Yes | General + Novell |
PathScale | 2003 | PathScale | No | MIPS |
FPGA C | 2005 | Bass | Yes | FPGA |
TCC | 2005 | Fabrice Bellard | Yes | Various libraries |
CLang | 2007 | LLVM Developers | Yes | General |
XL C | 2007 | IBM | No | IBM systems |
HP-C | 2012 | HP | No | HP systems |
AOCC | 2017 | AMD | Yes | AMD systems |
Beyond this, there are several other compilers that were not used by a significant number of users and originated from several sources like:
- University research projects
- Backed by companies but failed to get users
- Experimental projects by a small group of developers
Why did some compilers go out of use?
One notable example is PCCM . It was widely used at a time as a general compiler but with the entry of better compilers like GCC, users moved from it.
Sometimes, backing companies are dissolved which results in downfall of the compilers like PathScale . Another example is CodeWarrior compiler which was mainly for Motorolla devices and due to its closure, this compiler went out of use.
For some the focus area went out of use. QuickC by Microsoft was for DOS and as Microsoft went on to develop better Operating System, they abandoned QuickC and developed better compilers for the new Operating Systems.
Why we need multiple compilers?
We need multiple compilers because:
- Instruction set that is optimized for a particular hardware systerm varies.
- Operating systems plays to significant role in execution.
Hence, a compiler can be optimized for:
- a particular Hardware system
- a particular Operating System
- Particular system load like distributed, real time and others.
For example: ICC by Intel is optimized for Intel Systems while AOCC is optimized for AMD systems. Other compilers like GCC focuses on general optimizations for hardware features which are fairly standard.
ACK compiler which came out in 1980 was optimised for OpenBSD operating system. Similarly, other compilers focus on different operating systems.
With this, you have a good idea of how compilers evolved over the years and how the focus of each compiler differ.
