Compiler Command-line Options Usage In the current version of RVCT, the compiler might place small global ZI data items in RW data sections as an optimization. In RVCT 2.0.1 and earlier, small global ZI data items were placed in ZI data sections by default. Use this option to emulate the behavior of RVCT 2.0.1 and earlier with respect to the placement of small global ZI data items in ZI data sections. Note Selecting the option --bss_threshold=0 instructs the compiler to place all small global ZI data items in the current compilation module in a ZI data section. To place specific variables in: • a ZI data section, use __attribute__((zero_init)) • a specific ZI data section, use a combination of __attribute((section))__ and __attribute__((zero_init)). Example int glob1, glob2; /* ZI (.bss) in RVCT 2.0.1 and earlier */ /* RW (.data) in RVCT 2.1 and later */ Compiling this code with --bss_threshold=0 places glob1 and glob2 in a ZI data section. See also • #pragma arm section [section_sort_list] on page 4-50 • __attribute__((section)) on page 4-44 • __attribute__((zero_init)) on page 4-48. 2.1.11 -c This option instructs the compiler to perform the compilation step, but not the link step. Note This option is different from the uppercase -C option. Usage The use of the -c option is recommended in projects with more than one source file. 2-12 Copyright © 2007, 2010 ARM Limited.

Choosing this option implicitly selects the option -E. Note This option is different from the lowercase -c option. See also • -E on page 2-33. 2.1.13 --c90 This option enables the compilation of C90 source code. Default This option is implicitly selected for files having a suffix of .c, .ac, or .tc.
