Compiler warnings when translating
Created originally on Bitbucket by mattip
There are many warnings when translating.
This one (one example of tens of such warnings)
[platform:WARNING] rpython_rlib_4.c: In function ‘pypy_g_TimSort_merge_collapse_13’: [platform:WARNING] /<path>/pypy/rpython/translator/c/src/int.h:32:30: warning: assuming \ signed overflow does not occur when assuming that (X - c) <= X is always true \ [-Wstrict-overflow] [platform:WARNING] #define OP_INT_LT(x,y,r) r = ((x) < (y)) [platform:WARNING] rpython_rlib_4.c:9390:4: note: in expansion of macro ‘OP_INT_LT’ [platform:WARNING] OP_INT_LT(l_index_11327, l_v2221820, l_v2221848);
is strange. All the values are
Signed which is
long. When I try to replicate with godbolt, I do not get that warning
We also discard
const qualifiers when accessing a struct field:
platform:WARNING] pypy_module_time.c: In function ‘pypy_g__init_timezone’: [platform:WARNING] pypy_module_time.c:370:11: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] [platform:WARNING] l_cp_134 = RPyField(l_res_2143, tm_zone);
There are many more warnings, but these overshadow the other warnings.
