The compilers were run on Debian GNU/Linux (for SDCC) or Windows 7 (others). Raisonance required various modifications (the modifications did not affect correctness or score they consisted of adding typedefs, renaming variables as data is a keyword for Raisonance, and make Coremark use global instead of local storage, since Raisonance does not support more than 256 bytes of local variables per function). For all compiler except Raisonance, Dhrystone and Whetstone sources from the tutorial were used directly. The benchmark results were output via the printf from the implementation and a custom putchar() onto an UART. For IAR, which has an inlining heuristic, inlining was disabled for Dhrystone regardless of optimization goal (as required by the official rules for the Dhrystone benchmark).

For the Cosmic compiler, +modsl0 was used to specify ≤64K code size, which corresponds to the default settings of the other compilers. The benchmarks were build with the different optimizing compilers with various optimization settings, and executed on an STM8AF5288 on the STM8A-DISCOVERY evaluation board. EC++:Embedded C++ was an attempt to standardize a subset of C++ suitable for embedded devices, which never became really popular: 'To the best of my knowledge EC++ is dead (2004), and if it isn't it ought to be.' (Bjarne Stroustrup).Compilers vendors and C programmers moved to ISO C11 rather quickly. C11: The latest standard is the 2011 ISO standard.The move from C89 to C99 was initially slow, with the ISO C99 standard slowly gaining ground over the years. C99: The 1999 ISO standard introduced major new features.It never became popular, with most users moving directly from C89/C90 to C99. C95: In 1995, some minor new features were introduced, resulting in what is commonly called the ISO C95 standard.This standard is usually referred to as ANSI C89 or ISO C90. C89: C was first standardized by ANSI in 1989, which (with minor fixes) became an ISO standard in 1990.The input language to be accepted by C compilers is defined by international standards, with the ANSI C89/ISO C90, ISO C99 and ISO C11 being the most important.
