32: /* This apparently trivial test is designed to detect missing .type and
33: .size directives in asm code, per the problem described under
34: GMP_ASM_TYPE in acinclude.m4.
35:
36: A failure can be provoked in a shared or shared+static build by making
37: TYPE and SIZE in config.m4 empty, either by editing it or by configuring
38: with
39:
40: ./configure gmp_cv_asm_type= gmp_cv_asm_size=
41:
42: mpn_add_n is used for the test because normally it's implemented in
43: assembler on a CPU that has any asm code.
44:
45: Enhancement: As noted with GMP_ASM_TYPE, if .type is wrong but .size is
46: right then everything works, but uses code copied down to the mainline
47: data area. Maybe we could detect that if we built a test library with an
48: object that had .size deliberately disabled. */
