10 | # If you want both to optimise and debug with the DEC cc |
11 | # you must have -g3, e.g. "-O4 -g3", and (re)run Configure. | |
12 | # | |
b971f6e4 | 13 | # * gcc can always have both -g and optimisation on. |
8a019ce7 | 14 | # |
b971f6e4 | 15 | # * debugging optimised code, no matter what compiler |
8a019ce7 JH |
16 | # one is using, can be surprising and confusing because of |
17 | # the optimisation tricks like code motion, code removal, | |
18 | # loop unrolling, and inlining. The source code and the | |
19 | # executable code simply do not agree any more while in | |
20 | # mid-execution, the optimiser only cares about the results. | |
21 | # | |
b971f6e4 | 22 | # * Configure will automatically add the often quoted |
f2c69087 JH |
23 | # -DDEBUGGING for you if the -g is specified. |
24 | # | |
b971f6e4 | 25 | # * There is even more optimisation available in the new |
f2c69087 JH |
26 | # (GEM) DEC cc: -O5 and -fast. "man cc" will tell more about them. |
27 | # The jury is still out whether either or neither help for Perl | |
28 | # and how much. Based on very quick testing, -fast boosts | |
29 | # raw data copy by about 5-15% (-fast brings in, among other | |
30 | # things, inlined, ahem, fast memcpy()), while on the other | |
31 | # hand searching things (index, m//, s///), seems to get slower. | |
32 | # Your mileage will vary. | |
8e964347 | 33 | # |
b971f6e4 | 34 | # * The -std is needed because the following compiled |
e60a08f8 JH |
35 | # without the -std and linked with -lm |
36 | # | |
37 | # #include <math.h> | |
38 | # #include <stdio.h> | |
39 | # int main(){short x=10,y=sqrt(x);printf("%d\n",y);} | |
40 | # | |
41 | # will in Digital UNIX 3.* and 4.0b print 0 -- and in Digital | |
42 | # UNIX 4.0{,a} dump core: Floating point exception in the printf(), | |
43 | # the y has become a signaling NaN. | |
44 | # | |
b971f6e4 | 45 | # * Compilation warnings like: |
46 | # | |
47 | # "Undefined the ANSI standard macro ..." | |
48 | # | |
49 | # can be ignored, at least while compiling the POSIX extension | |
50 | # and especially if using the sfio (the latter is not a standard | |
51 | # part of Perl, never mind if it says little to you). | |

85ab1d1d | 513 | # * Newer Digital UNIX compilers enforce signaling for NaN without |
313489a2 SB |
514 | # -ieee. Added -fprm d at the same time since it's friendlier for |
515 | # embedding. | |
516 | # | |
517 | # * Fixed the library search path to match cc, ld, and /sbin/loader. | |
518 | # | |
519 | # * Default to building -Duseshrplib on newer systems. -Uuseshrplib | |
520 | # still overrides. | |
521 | # | |
522 | # * Fix -pthread additions for useshrplib. ld has no -pthread option. | |

619 | # Because the dlopen, dlclose,... calls are in the | |
