* Add multiarch directories for arm and i386
* Fix detection of biarch: /lib64/ld-linux-x86-64.so.2 is mandated by
ABI and is thus always present, even if there is no biarch
* Define CONFIG_LDDIR directly with the right value in case of multiarch
instead of defining it to /lib and then redifining it.
This patch fix 2 bugs in CONFIG_LDDIR usage:
* CONFIG_LDDIR used for 2 purposes
there is confusion between the directory to find libraries, crt* files
and headers and the directory in which the program interpreter is.
These two directories are not related. The latter is specified by the
ABI and should not be configurable while the former depends on the
system (single arch, biarch, multiarch). This end a longstanding issue
with amd64 program interpreter later propagated to other architecture
interpreters.
* If multiarch is in effect, then the library directory should be /lib.
/lib64 denotes biarch architecture, everything which is here would be
in /lib/x86_64-linux-gnu instead.
This reverts commit 1c11b857fe.
On windows, libtcc.c is compiled with ONE_SOURCE and then tcc.c is
linked to it. Thus tcc.c can only use public functions which cstr_* are
not.
elements in linker_arg are used in TCCState structure and must thus not
be freed when option parsing is finished. Declare linker_arg as a global
static variable and free it after tcc_delete has been called on TCCState
structure.
This fix commit 7fb0482a46
ld support arguments to multiple-letter options being passed in two
ways:
* -opt=arg
* -opt arg
libtool generate command line of the second form. This commit add
support for the second form so that libtool works with tcc. The way it
is done is to concatenate all -Wl options into one and then pass it to
set_linker.
Remove the previous logic to link a named file with a loader script by
using tcc_add_dll instead. Hence, all files can be linked, not only
files ending in .so/.def.
