* cross-compilers: allow individual configurationgrischka2017-02-231-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | since configure supports only native configuration a file 'cross-tcc.mak' needs to be created manually. It is included in the Makefile if present. # ---------------------------------------------------- # Example config-cross.mak: # # windows -> i386-linux cross-compiler # (it expects the linux files in <prefix>/i386-linux) ROOT-i386 = {B}/i386-linux CRT-i386 = $(ROOT-i386)/usr/lib LIB-i386 = $(ROOT-i386)/lib:$(ROOT-i386)/usr/lib INC-i386 = {B}/lib/include:$(ROOT-i386)/usr/include DEF-i386 += -D__linux__ # ---------------------------------------------------- Also: - use libtcc1-<target>.a instead of directories - add dummy arm assembler - remove include dependencies from armeabi.c/lib-arm64.c - tccelf/ld_add_file: add SYSROOT (when defined) to absolute filenames coming from ld-scripts

| | | | | | | | | | | | | | | | | | | | | | | | | | | | - tccgen.c/tcc.h: allow function declaration after use: int f() { return g(); } int g() { return 1; } may be a warning but not an error see also 76cb1144ef91924c53c57ea71e6f67ce73ce1cc6 - tccgen.c: redundant code related to inline functions removed (functions used anywhere have sym->c set automatically) - tccgen.c: make 32bit llop non-equal test portable (probably not on C67) - dynarray_add: change prototype to possibly avoid aliasing problems or at least warnings - lib/alloca*.S: ".section .note.GNU-stack,"",%progbits" removed (has no effect) - tccpe: set SizeOfCode field (for correct upx decompression) - libtcc.c: fixed alternative -run invocation tcc "-run -lxxx ..." file.c (meant to load the library after file). Also supported now: tcc files ... options ... -run @ arguments ...
* arm: Provide alloca()Michael Matz2014-04-051-0/+11
This provides a simple implementation of alloca for ARM (and enables the associated testcase). As tcc for ARM doesn't contain an assembler, we'll have to resort using gcc for compiling it.
