I have a hash function hash(T v) overloaded for
all integral types. I want to provide a variant for
float and double, which should work as follows:
take the floating-point value, treat its binary
representation as uint32_t/uint64_t and use
the result as a parameter for an integral hash().
However,
Hi everyone,
I am porting GCC to a custom 16-bit microcontroller with very limited
addressing modes. Basically, it can only load/store using a (general
purpose) register as the address, without any offset:
LOAD (R2) R1; load R1 from memory at address (R2)
STORE R1 (R2) ; st

Oops, we can't actually always bootstrap libgomp - we shouldn't try if it's
not in target_configdirs.
Does the cygwin build work with the attached patch?

The use of anonymous structure does seem to be the problem. I also missed the
fact that the TYPE_DEF DIE is missing from the DWARF data. If the TYPE
_DEF DIE was in the DWARF data, I could still parse the anonymous type.
Do you think the TYPE_DEF DIE should be part of the output? Is this a GNU

It's a C extension, according to the documentation.

Most linkers do not use the -L path to search for file names on the

Hi Sergio. My port has similar addressing modes - all memory must be
accessed by one of two registers and can only be accessed indirectly,
indirect with pre increment, and indirect with post increment. The
key is GO_IF_LEGITIMATE_ADDRESS and the legitimate address helper
function. Mine looks lik

Not finished yet, but I may have seen a problem already:

This probably is a new version of PR41418 then. We have the problem that
fortran is turned on in --enable-languages, so libgomp configure expects the
fortran compiler to be available.
Does this fix it for you?

In general, it's not. But future versions of gcc may want changes to
current versions of glibc. We've seen that happen in the past, and it
is likely to happen again in the future. (E.g., we needed to use
