fix(ldgen): don't emit intermediate placements without sections
When a symbol needs to be placed to a different target than the one
designated for the object file, the object file is expanded, which
includes the following steps:
1. Creating a new placement for the symbol's input section with the
specified target.
2. Excluding the object placement from the orignal target.
3. Creating a new intermediate placement for the object for the original
target, where its input sections are expanded, excluding the input
section for the symbol.
Let's illustrate the object expansion process with the following example:
[sections:rodata]
entries:
.rodata+
.sdata2+
.srodata+
[scheme:default]
entries:
text -> flash_text
rodata -> flash_rodata
[scheme:noflash]
entries:
text -> iram0_text
rodata -> dram0_data
[mapping:soc_pm]
archive: libsoc.a
entries:
gpio_periph: GPIO_HOLD_MASK (noflash)
gpio_periph section headers:

1. Creating a new placement
.dram0.data :
{
*libsoc.a:gpio_periph.*(.rodata.GPIO_HOLD_MASK .sdata2.GPIO_HOLD_MASK .srodata.GPIO_HOLD_MASK)
}
2. Excluding the object placement
.flash.rodata :
{
*(EXCLUDE_FILE(*libsoc.a:gpio_periph.*) .rodata.* ...)
}
3. Creating a new intermediate placement
.flash.rodata :
{
*libsoc.a:gpio_periph.*(.rodata.GPIO_PIN_MUX_REG)
}
Now, let's do the same, but also move GPIO_PIN_MUX_REG to noflash with an updated mapping.
[mapping:soc_pm]
archive: libsoc.a
entries:
gpio_periph: GPIO_HOLD_MASK (noflash)
gpio_periph: GPIO_PIN_MUX_REG (noflash)
1. Creating a new placement
.dram0.data :
{
*libsoc.a:gpio_periph.*(.rodata.GPIO_HOLD_MASK .sdata2.GPIO_HOLD_MASK .srodata.GPIO_HOLD_MASK)
*libsoc.a:gpio_periph.*(.rodata.GPIO_PIN_MUX_REG .sdata2.GPIO_PIN_MUX_REG
.srodata.GPIO_PIN_MUX_REG)
}
2. Excluding the object placement
.flash.rodata :
{
*(EXCLUDE_FILE(*libsoc.a:gpio_periph.*) .rodata.* ...)
}
3. Creating a new intermediate placement
.flash.rodata :
{
*libsoc.a:gpio_periph.*
}
The *libsoc.a:gpio_periph.* entity in step 3 no longer has input
sections, as there are no remaining .rodata input sections in the object
file. The linker behavior for this mapping is to include all object
input sections that have not yet been placed as described in
https://sourceware.org/binutils/docs/ld.html#Input-Section-Basics
"If you use a file name without a list of sections, then all sections in
the input file will be included in the output section. This is not
commonly done, but it may by useful on occasion."
The map file for such mapping now contains following input sections
.flash.rodata 0x3c0a0120 0x19b34
*libsoc.a:gpio_periph.*()
.debug_info 0x3c0b95bf 0xd8 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_abbrev 0x3c0b9697 0x70 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_aranges
0x3c0b9707 0x18 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_line 0x3c0b971f 0x1ab esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.debug_str 0x3c0b98ca 0x21a esp-idf/soc/libsoc.a(gpio_periph.c.obj)
0x22d (size before relaxing)
.comment 0x3c0b9ae4 0x30 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.note.GNU-stack
0x3c0b9ae4 0x0 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
.riscv.attributes
0x3c0b9ae4 0x44 esp-idf/soc/libsoc.a(gpio_periph.c.obj)
This is incorrect, and such intermediate placement should not be
generated. This type of placement can be recognized because it is not
explicitly defined in the mapping and lacks input sections. We can
identify this in the significant function and prevent issuing commands
for such placement.
