Hi, I would like to begin contributing to the GCC project, and Segher
suggested that I should take care of the copyright assignment forms.
I am reaching out to obtain them. I am currently unemployed so there's
no issue with an employer.
Thanks

Hi,
I have posted a patch series [1] for converting some of the RTL code to
use predicate macros, as described in the suggestions for beginner GCC
projects [2]. Segher was kind enough to give some comments on the
initial posting [3].
The code has been bootstrapped natively on x86_64, and I have bu

gcc 9 when configured for fortran installs ISO_Fortran_Binding.h in
gfor_cdir =
$(libdir)/gcc/$(target_alias)/$(gcc_version)$(MULTISUBDIR)/include
For x86_64's 32-bit architecture support, this creates a subdirectory named
'include'
inside $(libsubdir)/32 which didn't use to exist in gcc

While building clang-8.0.0 or firefox-66.0.3 on a gentoo system (x86_64)
gcc 9 release candidate runs out of memory with -O2 -ggdb. Gcc 8.3.0
succeeds without issues. For clang there are about 5-6 compilations
where the memory usage seems to grow without bound (I have 128Gb RAM +
128Gb swap and at
15 matches
