Exclude asm files which fail when building on w64 using mini-gmp.

parent 9c95a3d3
2015-03-31 Niels Möller <>
* x86_64/ecc-224-modp.asm: Require that GMP_NUMB_BITS == 64.
* x86_64/ecc-521-modp.asm: Likewise. Note that the other
ecc-*-modp.asm files happen to work fine on x86_64, with either 32
or 64 bits.
* asm.m4 (GMP_NUMB_BITS): New macro, expanding to nothing.
* Move tests for compiler characteristics,
libraries, and GMP_NUMB_BITS, before assembler-related tests.
For files in $asm_hogweed_optional_list, check if they declare
a GMP_NUMB_BITS requirement, and skip files which are incompatible
with the configuration. Needed for --enable-mini-gmp om w64.
* (clean-here): Unconditionally delete *.a (including
stub libraries like *.dll.a).
