* a statement expressions with a pointer return typeseyko2015-03-031-1/+5
| | | | | | | | | | | | | A test program: ////////////// int main() { void *p = ({ 0 ; ((void *)1); }); } ///////////// Porblem is introduced in a commit a80acab: Display error on statement expressions with complex return type This error is exposed when compiling a linux 2.4.26. tcc 0.9.23 can sucessfully compile this version of the linux.

* Add a debug info when a #line directive is handled.seyko2015-03-031-0/+2
| | | | | The problem was: a debug info for the file which contain a #line directive (for example a preprocessed one) was wrong.
* Revert a grischka patch: gdb refused to know "main"seyko2015-03-031-1/+1
| | | | | | | | | | | | | | | It is a strange patch because before this commit a gdb is working well and after this commit there is exactly the same problem on Linux: gdb refuses to know "main" Author: grischka <grischka> Date: Tue Feb 5 21:18:29 2013 +0100 tccelf: fix debug section relocation With: tcc -g hello.c gdb a.out b main gdb refused to know "main" because of broken dwarf info.
* pp-many-files: don't drop a preprocessor defines when tcc going to ↵seyko2015-03-031-4/+0
| | | | | | | | | | | | | | preprocess a next file in the same pass like tcc -E one.c two.c three.c -o combined.i This will allow to speed up a compilation process by using a commamd like tcc -E *.c | tcc -o program.exe -xc - It looks that multi-times initialization don't affect anything. Only call to the free_defines(define_start) in tcc_preprocess() is removed in assumption that free_defines(NULL) in tcc_cleanup() will free all defines.
* A gcc preprocessor option -dD addedseyko2015-03-034-22/+84
| | | | | | | | | With this option on a defines are included into the output (inside comments). This will allow to debug a problems like: In file included from math.c:8: In file included from /usr/include/math.h:43: /usr/include/bits/nan.h:52: warning: NAN redefined
* Added a gcc preprocessor options -P, -P1seyko2015-03-034-10/+46
| | | | | | | | | | | tcc -E -P do not output a #line directive, a gcc compatible option tcc -E -P1 don't follow a gcc preprocessor style and do output a standard #line directive. In such case we don't lose a location info when we going to compile a resulting file wtith a compiler not understanding a gnu style line info.

* A preprocessor should Interpret an input line "# NUM FILENAME" as "#line NUM ↵seyko2015-03-031-1/+6
| | | | | | | | | | | FILENAME" A cpp from gcc do this. A test case: tcc -E tccasm.c -o tccasm.i tcc -E tccasm.i -o tccasm.ii After a patch the line numbers in tccasm.ii are the same as in tccasm.i

* aarch64: Fix -run.Michael Matz2015-02-232-10/+54
| | | | | | | This adds some more support for properly transfering some offsets over the different stages of a relocations life. Still not at all psABI compliant and DSOs can't yet be generated. But it runs the testsuite in qemu-arm64.

* Fix handling of case_reg in switch statement.Edmund Grimley Evans2015-02-201-0/+3
| | | | | | The back end functions gen_op(comparison) and gtst() might allocate registers so case_reg should be left on the value stack while they are called and set again afterwards.

| | | | | | | | | | | Add a ".i" extension as alias for ".c" GCC and file extensions: .i C source code which should not be preprocessed. Before a patch: ./tcc -E tccasm.c -o tccasm.i ./tcc -c tccasm.i -o tccasm.o tccasm.i:1: error: unrecognized file type

* tcc.h (BufferedFile): Remove unnecessary static memory allocationLee Duhem2014-12-111-1/+1
| | | | | The memory needed by `buffer' will be allocated in `tcc_open_bf', these is no need to allocate them in BufferedFile statically.
* libtcc.c (put_extern_sym2): Extend the scope of buf to match its useLee Duhem2014-12-111-2/+1
| | | | | After leaving the code block that `buf' is defined, `buf' will not exist, so `name' will point to a variable that does not exist.
