| /* |
| This test program is typically run indirectly, by the "puffs test" or "puffs |
| bench" commands. These commands take an optional "-mimic" flag to check that |
| Puffs' output mimics (i.e. exactly matches) other libraries' output, such as |
| giflib for GIF, libpng for PNG, etc. |
| |
| To manually run this test: |
| |
| for cc in clang gcc; do |
| $cc -std=c99 -Wall -Werror gif.c && ./a.out |
| rm -f a.out |
| done |
| |
| Each edition should print "PASS", amongst other information, and exit(0). |
| |
| Add the "puffs mimic cflags" (everything after the colon below) to the C |
| compiler flags (after the .c file) to run the mimic tests. |
| |
| To manually run the benchmarks, replace "-Wall -Werror" with "-O3" and replace |
| the first "./a.out" with "./a.out -bench". Combine these changes with the |
| "puffs mimic cflags" to run the mimic benchmarks. |
